NAS Access in Catalina issues

Since upgrading to Catalina my access to NAS shares is problematic.

I have a QNAP NAS unit, with APFS and SMB (1/2/3) enabled.

I can see the NAS in finder under 'Locations' but when I click on the NAS I get 'connection failed'. Using 'Connect As' does nothing at all.

I manage to connect using 'Connect to server' with the command: afp://NASNAME(AFP)._afpovertcp._tcp.local

It asks me which 'share' I want to connect and all works well.

If I then go back through finder to the same share I get the same 'connection failed' issue, even though the mounted share shows on my Desktop.

Any ideas please?

Mac mini 2018 or later

SPOILER ALERT: this is not a solution but a "working" WORKAROUND

My actual situation:

I'm able to access to my NAS (SMB shares) through finder left sidebar only after a reboot
I'm Always able to connect to my SMB shares by "command K"
my NAS implements SMB v3_2 protocol

My workaround (tested working after several working time or sleep):

reboot the mac
connect to NAS through sidebar network shortcut. This will mount shares on the desktop
drag the shares icons on your desktop on finder sidebar but in "favorite" section (as in attached picture)

Now, every time you need to access these shares use these links on favorite sections instead of the one in network.

This definitely demonstrates that is not a "protocol connection issue" but a Finder specific issue.

I think Catalina is the first major Apple OS I will skip, because of the SMB problems.

Am considering downgrading myself.

A bit dissapointed that quality has taken such a big step backwards.

@Tom Hodgson could you repeat what you did to solve the issue on your setup? Maybe share what setup you have also? (NAS, douter, config)?

I have to add I tried the DNS flush also with sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder and that didn't help. Flushed cache, rebooted, and problem was there immediately.
