Total Commander

Since years i used the total commander for androit and the LAN plugin on my tablet Samsung Galaxy S4 and my smartphone Samsung Galaxy S22 Ultra.
My Server is a Qnap NAS.
The connection from Windows PC always OK.
The connection from the tablet is always OK.
The connection from the Galaxy S22 gives me the following answer:
SMB2 connect:failed to connect to /(IP-Adresse) (port 445) from /10.14.0.2 (port 47xxx) after 5000ms: isConnect failed:
I used the correct IP adresse and I try the server name instead. Nothing works.
If you know this trouble please help.
Thx

I have a Samsung S20 and an A54 and they both work fine with the LAN plugin. I use the server name (just the name, no \\ in front) and only SMB2 is checked in the settings

Thank for your reply.
A friend of mine told me he reboot his smartphone twice and then it works fine.
I try it - and really the LANplugin works now fine.

Thank to all
