Catalina SMB problem

I have tried all sorts of stuff to get this to remain connected and I have yet to find something that works. I get error's that it cannot connect. Now this is not perfect, but it works. Once it respawn's everything works as it should. The problem with is I only get 24-ish hours before it craps out. What we need is a real fix for this. Whether it's SMB or AFP neither holds a connection to the NAS. Now in my instance I'm using a 2017 Netgear ReadyNAS 424. Bottom line, it works.

Just happened again, tried to relaunch the finder, but it didn't fix. When I try to connect to the SMB I get the small "connecting" window, but it never connects. Thanks for sharing, but rebooting seems to be the only working fix in my case.

Not a fix, but at least better than rebooting: Go to System Preferences, Sharing. Untick "File Sharing" and then tick it again. This will restart some services. It fixes the issue for me temporarily without rebooting.

I have the same issue, my Huawei must be using SMB 1 or 2, but it doesn't have support for SMB3. It seems like Apple has removed support for SMB 1 and 2, I am sick of Apple doing this ****. Do they have any respect for their users, we all can't upgrade just because Apple wants us to. Why would you remove support for old protocols????? I had no issue with connecting until I downgraded to Catalina. F^$K Apple, I'm going back to windows on my next computer.

Apple is not here to read your thinly disguised epithets. Please address them via https://www.apple.com/feedback/ though it would be more productive if you defined the problem for them there rather than using your post as a rant

A quasi-technical answer to removing support for old protocols is that security holes may be insoluble in old versions, so the industry moves on. Upgrade your NAS firmware if you have not done so already, and work from there

It has been suggested that a problem with a new OS X usually allows a free support call. Ask Apple. They can decide

Yes. search for: reverting to Mojave from Catalina with any good search engine.

Just drag the folder to the navigation column

I have the same problem, it works only if drive accept anonimus connection. Soon the I add her and password it fail to connect.

jessika67 - actually its the first problem I've ever had with that OS since I start using it 5yrs ago and compared to Win* its light years ahead (and I was using the Win for about 15yrs.). So if you are not gonna give any practical solution, please dont waste your time and just go and make your hubby a sandwich.

Same here. I can connect randomly, but sometimes it's so slow that the entire system collapses and I have to reboot. Not even a shut-down, start works, as it keeps the slow transactions I'd already started, on process.

Deleting the finder preferences didn't fix the problem for me. After a while the mappings have disconnected and I can't reconnect them. I also tried to force a restart of the finder, but that didn't work either. The only known workaround in my case is a complete reboot of the computer which isn't convenient.

I'm sure I made it clear, Apple removed support for SMB1 and SMB2. I am not going to buy new hardware, my router doesn't have the appropriate support for SMB 3.

Is that a way to bring back support for SMB1 and SMB2?

If not, Is there a way to go back to the previous OS?
