Anki Help

16.8.2020
Anki-Desktop Version 2.1.28 on Windows 10 rev.2004
When I try to sync then the above error occurs. I made the following effort to fix it:

  • Update to 2.1.30: no change
  • deinstalled Anki, restart, new install including deletion of profiles: no change
  • new user in Ankiweb corresponding to new profile in Anki: no change
  • extensive search in google: no findings

Does anyone has the same effect or even better knows a remedy?

Your antivirus or firewall is likely blocking Anki, or your proxy is not configured correctly.

Problem solved.
You are right. I switched off firewall and proxy and the problem disappeared. Not so nice: Switching it on again, the effect did not come back.

For others who might overcome this problem:
The error message persists even when you give wrong login or wrong password. This means the program does not reach password check. The problem is before.

@dae: Thank you for your help.

I was still fighting against this problem until today. Now I know the reason. As dae said the proxi was not configured correctly. But she didn’t say what.
If you also have this problem: If you use a proxi make sure that it is not used for local addresses.

Still my postings before were not the end of the story. The problem came back.

I realized that the windows proxy settings were set from off to on. The entry was engaged by something I had not put in. The setting was Address 127.0.0.1 Port 8003. It turned out that the program trustedlogos was listening here. I used hints from here (How to remove TrustedLogos adware (Virus Removal Guide)) to remove this annoying brat.

I am pretty sure that the spook is gone now.
