I am using NC 11 (recently upgraded) and at some point my ubuntu client stopped connecting. The client logs says

When accessing throught web it works ok. Recently we have changed our server certificate, I don’t know if this could be related.

Thanks

Removing the account and adding it again solved the problem. I compared the /home/user/.local/data/ownCloud/owncloud.cfg and the differences are:

NOT WORKING

Bonjour !

I have the same problem.
Recently I have changed my password, I don’t know if this could be related.
Removing the account and adding it again solved the problem.

Do you solve your problem ?

I reinstalled the client, never learned why this happened.

UPDATE:
ok, so the issue for me appears to be the bruteforce protection feature on the NC server. I don’t know all of the options, but if you can use phpmyadmin to access your database tables and clear out the entries inside the “oc_bruteforce_attempts” table, it should solve the issue.

===========================
I’m seeing this issue suddenly also. I cannot explain what is happening. I made NO CHANGES to the client.

My other clients are JUST FINE.

I have been doing work on my server, but the server application is isolated from the OS packages (unless it is fundamental). And I did not change the NC server.

Here is the kicker. If you add a new account in the NC client - it will sync without issue. If you close and re-open the client, it will fail to sync. Repeat the add of that same user and it will sync again.

The same here with NC 13.0.2 and client 2.3.3

In client logs we find:

QIODevice::read (QNetworkReplyHttpImpl): device not open

Workaround:

Clear Bruteforce attempts database with:

delete from oc_bruteforce_attempts;
