Sometimes cannot login, "WebClientRequestException: Connection reset"

0

Trying to login in the client, I get an error message instead of being logged in (error message provided at the end of the message)
I updated the client to the newest version, still had the issue.
It ended working on the 3rd (or 4th?) try.

Elmi reported the same bug here, but in a thread started by a different error message - thus I'm creating this new thread as the cause may differ.

Educated guess: it's due to the ongoing server issues + lack of retry on the client side, right ?

Happy bug hunting (one can dream)

Error message :

Yes. The server is constantly refusing connection for no obvious reason.
