Can't connect to any network drive or shares, after updating to 26.2.

And can´t connect to my timemachine back-up via WiFi or ethernet anymore.

I'm I the only one?

Mac mini, macOS 26.2

An endemic issue with macOS 26.2 would usually have reports in the forums and some big 🤬 threads, so probably something local.

If you are running Samba, make certain your servers are not running Samba 4.22.

Either older, or 4.23.4 or later, 4.22.6 or later, if I read the release notes correctly.

(Based on another thread not yet fully resolved…) Do you (not) have two-factor authentication enabled?

Mine ended up being a DNS issue with a custom DNS I had set to my wifi interface.

I've got the same issue. Other devices on my network work fine and my machine took the update over the weekend.

Did you find a solution?

Right now trying to reinstall Tahoe, via recovery-mode. I’ll get back if it works or not.

Reinstalling Tahoe did not work. Still can’t mount any networkdrives. Or connect to my NAS via the browser.
