Ubuntu Desktop client not connecting - error thrown -

I’m running Nextcloud 10 on an ubuntu server… I can access the server via the web interface as well as with my mobile devices but my desktop client will no longer connect (it stopped connecting this afternoon). Here’s the error it has created

Thanks for any help,

It basically means the file transfer was interrupted in some way. The complete file was not uploaded. This could be anything from a time out on the server, to a firewall interfering or just a network drop out.
