403: Too many unsuccessful login attempts. Please restart transmission-daemon.

[amandamana]

The remote access web interface when set to require authentication stops working after a few days, apparently due to erroneously detecting a brute force attack. I've seen this using a normal install of version 3.00 on macOS in a secure LAN, where actual unsuccessful login attempts are extremely unlikely.

This issue was seen as far back as Oct 2020.

More information in this longer thread of both docker and normal installations.

Can confirm - quite annoying at times.
There seem to be changes in master (see pull #1447) that allow configuration and the ability to disable the brute force protection but no official release for that yet.

Can also confirm. Logins are limited to IPs on my machine so I know it's not external unsuccessful logins.

I have upgraded my debian from buster to bullseye and this induced transmission to be upgraded from 2.94 to 3.0 . Previously with transmission 2.94 or even older versions I did not have this issue. Could anybody support us somehow, to avoid this issue?

Any news on that ?

Sorry, I have forgotten to reply on this topic. In my case I had a perl script triggered by cron. This script tried to gain up- and download statistics information into an rrdtool database. Something was wrong with that script, I did not bother with it at least 1 year. I simply deactivated that script because it was not really important for me and since some weeks transmission 3.0 is working fine for me.
