There is an active issue with AnkiWeb – Account-specific sync failure on Anki Desktop and AnkiMobile – but that hasn’t been going on for days, so I don’t think that’s what has been causing problems for you.
Once that issue is resolved, I will be able to look at your account. But if you can access it on the AnkiWeb site, it seems unlikely it is locked.
There are other things you can try – Error establishing a secure connection when syncing - Anki FAQs – but wait until the active issue with the servers is resolved.
