Question: Catalina SMB problem

I have issue after updating to macOS Catalina Version 10.15 on macbook pro 2017.

I have a network drive(HD) connected to a router using SMB:// Fritz-nas

This has always connected automatically and is primarily used as a music . Since the update this has been unavailable and if I try to connect I get the error :

"There was a problem connecting to the server "ServerName". The server may not exist or it is unavailable at this time. Check the server name or IP address, check your network connection, and then try again."

If I try to browse it shows the drive but will not connect. This is shared with a Windows 10 machine and that can connect as normal.

Any help would be appreciated.

I have a similar question posted in the Desktop area. My iMac keeps asking "You are attempting to connect to server xyz" with option to Cancel/Connect, but then fails to connect. I presume it is the same issue. It does not stop presenting this message which is very annoying. Do you have the same prompt? Have you been able to find a solution already? My server (Netgear Stora) does seem to connect through finder using the AFP:// connection, but this does not prevent the message from showing up. Regards, Henk

Check you NAS is broadcasting the correct Bonjour credentials.

You may need to reboot NAS, Router and Mac at some point in this battle (that started with Catalina for many of us). Choose a logical order if so. I'd want the router back first the NAS second and the Mac third

You might also want to add your NAS to your login items in system preferences

I was not able to connect my year 2011 iMac to my year 2019 iMac that was running Catalina. Prior to the upgrade to Catalina, I had no issues in this regard. I set both iMacs to use SMB rather than AFP. This in itself did not solve the issue. I then powered down both computers and my router. I then powered up my router, then I powered up the year 2011 iMac, and then finally I powered up my year 2019 iMac. I was then able to connect via Finder on my year 2019 iMac by clicking on Network in the sidebar of Finder and then I selected the year 2011 iMac. I then entered my computer password in the pop-up window.

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.

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.
