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'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?

Catalina does not support all devices that work with SMB1, the same must be updated by the respective manufacturers.

With the Fritz 7590 modem I had the same problem, now the manufacturer has updated to SMB3 and everything, with Catalina, works perfectly !!!

Hello,

you should fix it by installing the Cyberduk extension.

Hello,

this is not fix - this is a workaround and we need fix.

Correct, a workaround is not a fix & I have the same issue - it'd be nice to know what that fix is, or when it'll be arriving.

Try connecting using the IP address of the NAS after allocating it fixed IP in your router

Nope, it doesn't work. I just returns "mount_smbfs: server rejected the connection: Authentication error" and I'm pretty sure that I'm using correct credentials.

I had to use afp://<servername> to get it to work.

Go to "force quit" and relaunch the finder first and then connect to server, I don't know why this should work, but it does for me.

AFP ist ein Uralt Protokoll welches nicht mehr weiter entwickelt wird und somit unbrauchbar ist. Dazu kommt das Apple nicht mal SMB kann! Jeder Taschenrechner kann SMB XD

For me restarting finder does resolve the issue temporarily (holding OPTION and then right click Finder to restart) but after a day or sometimes 2 days I get the same error again.
