SSH FS suddenly not working

I was using the SSH FS extension with VS code just fine until yesterday, but all of a sudden it’s not working with the connection hanging forever. I’ve tried everything I could think of: restarting VS code, reinstalling the extension, killing all SSH processes from both local and remote server, removing any potentially affected cache files, etc., but nothing has worked. I’m not sure how to debug this because nothing is showing up in my output log in vs code and not sure where else to look. Any help would be greatly appreciated. Thank you.
