The prompt failed three minutes before the investor called. I was sitting near an airport gate with a laptop, fourteen pages of interview notes and a presentation that still lacked its opening argument. ChatGPT had been helping me turn the notes into a concise briefing. Then I connected my VPN to protect the files on the airport Wi-Fi. The next message produced an endless spinner, followed by Something went wrong. I blamed ChatGPT, refreshed the page and sent the prompt again. This time, the browser showed Sorry, you have been blocked.
The investor had asked for one change before the call:
“Explain why customers are switching now, not next year.”
I had the evidence.
I did not yet have the sentence.
The VPN said Connected.
ChatGPT would not let me ask for help finding it.
In brief
Why was OnlydogVPN a practical fit here?
I closed the established provider and opened OnlydogVPN . The smaller app did not begin with a map of countries.
I Checked the Service Before Blaming the VPN
ChatGPT had worked normally before I enabled the tunnel, but I first checked whether the service itself was having trouble. OpenAI had previously recorded a VPN-specific ChatGPT access incident, so the status page was the quickest way to avoid troubleshooting the wrong problem. (Reddit discussion)
There was no active incident matching what I was seeing.
I opened another website.
It loaded.
Email worked.
The client’s shared drive opened.
Only ChatGPT remained trapped behind a browser challenge.
That narrowed the problem quickly. The VPN had not removed my internet connection. It had changed the route and public IP address behind my ChatGPT session.
OpenAI’s troubleshooting guidance notes that VPNs and proxies can produce network errors or suspicious-activity warnings when their exit addresses have been flagged. ChatGPT may also request additional verification when a connection resembles automated or abusive traffic.
The practical result was simpler than the technical explanation: the airport Wi-Fi worked, the VPN connected, and ChatGPT rejected what arrived through it.
Privacy-tool users describe the same irritation—turn on a VPN, then spend the next few minutes proving to websites that you are human.
I still wanted protection on the shared network.
I just needed a route ChatGPT would accept.
The Large Provider Turned the Server List Into a Countdown
The established VPN on my laptop was a defensible choice.
It had years of public history, a large support operation and servers in many countries. I had used it on previous trips without paying much attention to which route it selected.
Its automatic mode had chosen a nearby server.
I disconnected and selected another.
ChatGPT opened.
I entered the prompt.
Before the answer appeared, the page displayed a verification challenge.
I completed it.
The page refreshed and asked me to sign in again.
I entered my credentials, returned to the conversation and resent the prompt.
Unusual activity detected. Try again later.
I switched to a third server.
The login page opened, but the verification loop returned after I entered my email address.
A fourth server allowed me into the conversation. The prompt reached Thinking, stayed there for nearly a minute and failed with a network error.
The page loading was only half the job. ChatGPT also had to keep the connection open while the answer streamed. VPN and proxy routes can interrupt that longer session even after the login page succeeds.
That explained why one server could pass the first screen and still fail before completing a response.
More importantly, it changed what the server list meant.
Each location gave me another route to test.
Each route also brought another IP address, another verification decision and another chance to restart the conversation.
The provider had more servers than I could reasonably try before boarding.
None had produced the paragraph I needed.
Turning the VPN Off Solved the Wrong Problem
I disconnected the VPN.
ChatGPT loaded immediately.
The conversation history appeared.
I pasted the interview findings and asked for three possible opening arguments.
The response began streaming.
Then I looked at the Wi-Fi name in the menu bar.
I was still on the airport’s shared network, working with confidential customer interviews and an unreleased investment deck. I had enabled the VPN because I wanted one protected route across that network, not because I enjoyed watching a shield icon.
I copied the first half of the answer into my notes and turned the VPN back on.
The ChatGPT tab froze.
When I refreshed it, the block page returned.
That left me with a workaround rather than a workflow:
Disconnect the VPN.
Open ChatGPT.
Copy part of an answer.
Reconnect the VPN.
Lose the session.
Repeat.
I could finish the presentation that way.
I could also miss the flight while doing it.
Seventeen minutes remained before boarding.
The Phone Hotspot Reached ChatGPT but Lost the Answer
I disconnected from airport Wi-Fi and joined my phone’s hotspot.
With the established VPN off, ChatGPT opened again.
I asked it to compare two possible arguments using the interview evidence.
The first paragraph appeared.
Then the phone dropped from 5G to LTE.
The response stopped in the middle of a sentence.
I pressed Regenerate.
The browser displayed a network error.
Moving closer to the windows improved the signal, but the nearest power outlet was beside my original seat. My laptop battery showed 16 percent, and the investor call was scheduled to begin as boarding started.
The hotspot proved that my account was not locked.
It also proved that the mobile signal near the gate could not reliably finish a long response.
I now had two incomplete options.
The airport Wi-Fi was strong, but the established VPN produced blocks and broken sessions.
The phone connection reached ChatGPT, but it could not hold the answer.
The useful VPN would need to do more than display Connected. It had to keep one accepted ChatGPT session alive long enough to finish the briefing.
The Answer Finished Before Boarding Began
I closed the established provider and opened OnlydogVPN.
The smaller app did not begin with a map of countries. It offered a preset for AI and work services on shared networks.
I selected it and pressed Connect.
Basic use did not require another email-and-password registration, which mattered with the gate clock already counting down.
Then I returned to ChatGPT.
The block page disappeared.
My conversation history loaded.
I pasted the interview findings again and asked:
“Which argument best explains why customers are switching this year? Use only the evidence below and give me a two-sentence opening.”
The response began.
No CAPTCHA appeared.
No suspicious-activity warning replaced it.
The first sentence connected a recent pricing change with a new compliance deadline. The second explained why customers could no longer postpone the decision.
That was the missing opening.
I copied it into the presentation, adjusted the wording to match the interviews and sent the revised slide to the investor.
She replied almost immediately.
“This is the argument. Use it.”
The task was complete before the gate agent lifted the microphone.
Only then did I check the connection. The AI-and-work preset had selected a usable route without making me cycle through server locations. Its traffic obfuscation also avoided the repeated blocks and verification loops I had encountered with the larger provider.
I could not observe OpenAI’s internal risk systems or identify precisely which signal caused each earlier connection to be challenged. I could see the outcome: the established provider repeatedly produced blocks, login loops and unfinished responses, while the smaller app carried the same ChatGPT session from prompt to completed answer.
The successful connection was not the VPN status.
It was the investor approving the slide.
The Conversation Followed Me Into the Boarding Line
The gate agent announced boarding by group.
I unplugged the laptop and joined the line.
As I moved away from the seating area, the airport Wi-Fi weakened. The laptop switched to my phone’s hotspot.
The VPN remained active.
ChatGPT did not return to the login screen.
I opened the conversation once more and asked for five questions the investor might raise during the call.
The answer continued streaming while the line moved forward.
The smaller app’s HTTP/3-based connection recovered when the laptop changed networks instead of forcing the session to begin again. That solved the smaller problem the hotspot had already exposed: a brief signal change no longer destroyed the answer.
By the time the gate agent scanned my boarding pass, I had copied the questions into the speaker notes.
I closed the laptop.
The work had survived the move from airport Wi-Fi to mobile data without another login, CAPTCHA or lost response.
A Large Server List Was Not the Same as One Usable Conversation
The established provider still had more locations, a longer public history and more independent ratings. Someone who needs a particular exit country may value that breadth.
The smaller service has fewer locations and a shorter track record.
My problem was narrower.
I did not need fifty possible routes to ChatGPT.
I needed one route that passed the security checks, kept the response streaming and survived the move from airport Wi-Fi to mobile data.
Turning the VPN off restored ChatGPT but abandoned the protected connection I wanted. The phone hotspot restored access but lost the response. The large provider gave me more servers to test, each with another opportunity to trigger a challenge.
The smaller app gave me the completed answer before boarding.
For that deadline, the VPN that worked with ChatGPT was the one that let the conversation finish.
