Signal Beta: Captcha verification says it succeeds, but I'm prompted to redo captcha verification.

[Geremia]

Using a supported version?

• I have searched searched open and closed issues for duplicates.
• I am using Signal-Desktop as provided by the Signal team, not a 3rd-party package.

Overall summary

Captcha verification says it succeeds, but I'm prompted to redo captcha verification. This continues in a loop (similar to some other issues , like #5821).

Steps to reproduce

1. Open Signal Desktop Beta
2. Click "Continue" to captcha verification.
3. Solve the captcha in browser.
4. Open the link back in Signal Beta.
5. It says verification successful, but it prompts to do captcha verification again.

Expected result

That it not prompt me again to do catpcha verification.

Actual result

It goes into a loop of prompting me.

Relevant part after going through a few iterations of the re-captcha loop:

@cuu508 here said:

Submitting a CAPTCHA solution to Signal does not affect the send attempts that already failed. It increases the chances that future sends will succeed.

Is this why I'm getting this issue here? I was trying to resend a message that failed, but in non-beta Signal Desktop, I am able to send the message to the recipient, so the captcha verification did work, despite Beta re-prompting me.

I am having the exact same issue on Desktop stable 7.0
Did not have this on 6.47.
I am currently am unable to use Signal desktop.

@tuxpizza sorry about that; can you share a debuglog?

pure empirical evidence: I also encountered this: captcha succeeded but signal desktop still wants me to verify. This happened when I was on vpn. When I took the vpn off the verification process went through.

Here's circular logic: using VPNs would sometimes trigger captcha verification, and if what i thought was true this verification cannot go through while on vpn...

@tuxpizza sorry about that; can you share a debuglog?

Same problem here, Linux Mint and Firefox. Tried to submit a debug log, but I get a popup
"Something went wrong with the upload! Please email support..."
Will send it now via email.

This is making Signal nearly unusable on my phone and Desktop.

Funny thing is too, is that I can skip verification and still send messages. So it doesn't even seem that the spam filtering even works.
