Today (05/01/2022), Fedora updated various system programs through its Discover program. Immediately afterward, Gnome’s Files file explorer refused to connect to my NAS. It now gives the following error:
"Unhandled error message: Failed to mount Windows share: Invalid argument"
Luckily, Plasma’s Dolphin file explorer continues to access the NAS without problem (and I can use my browsers to log into the NAS as usual).
Unfortunately, I don’t know how to see a log of what Discover actually upgraded. I know I saw some samba programs updated. But, there’s not much else I can tell you.
