Hello, I have a problem with one of my mailboxes. All of a sudden I am not able to fetch any e-mails. Here is the error message I could deduce: 2022-09-06 14:38:35.233000 UTC - [Parent 22912: IMAP]: D/IMAP URL failed with code 0x804b0014 (imap://bakur@imap.cern.ch:993/discoverallboxes) 2022-09-06 14:38:35.234000 UTC - [Parent 22912: IMAP]: I/IMAP 17b4331e800:imap.cern.ch:NA:ProcessCurrentURL: aborting queued urls 2022-09-06 14:38:35.235000 UTC - [Parent 22912: IMAP]: D/IMAP ImapThreadMainLoop leaving [this=17b4331e800]

I tried to delete the account and re-create it, I tired to install fresh version of TB (deleting my profile etc.), nothing helped. My `security.tls.version.min` is set to 1. In the meantime, I managed to access that very mailbox installing a fresh TB on a different machine. So the problem is with my current installation. But what can it be?

Thanks a lot in adnvace for you kind help!

If you really tried a fresh installation on the problem machine with a new profile, and it worked on one machine and not the other, that suggests the problem is outside of Thunderbird. You can try clearing the cache, but a fresh install would do that. Perhaps something in your internet settings on the problem machine like a VPN or proxy server is not correct? Sorry, I am grasping. But I would check your network settings on the problem machine.

Thanks for the suggestion! I have just reset network drivers/settings (Win 10). No improvement. I don't have VPN or proxy configurations.
