Unable to connect to LAN with latest rev 3.59 of TotalCmd-LAN

[TC-KA]

Thank you. Checked again, background data on both Android devices enabled. Each of their status bars say after the plugin start:
"TotalCmd-LAN (Windows-F...
Servername: Krotus-PC
Alle Verbindungen trennen"
This last line made me think a connection was established.

Addendum: FritzBox-Protokoll liefert zum Zeitpunkt des Einwahlversuchs 2MBit/s down und 75,6 kBit/s up für das Mobile.

I couldn't understand it's a name/password issue, since, without modifying anything, the connection is OK at the second try... (and sometimes at the first try)

But, nevertheless, maybe it's "almost" such issue, because, in my particular case, the login is anonymous : neither name nor password. I made it OK from my laptop standpoint, but could this be a problem for your plugin ?

Solution / reason found!
Disabling Windows Defender Firewall -> Private Network restored the access for both devices' Plug-in to the PC's files again.
It seems that either the recent Windows Update or Defender Update has locked out the LAN-Plugins.
Now it's the question if and how that "Private Network"'s Firewall can be configured such that it gives access to the Plug-Ins again even when activated.
In the meantime, thanks alot, Ghisler, for your patience!

EDIT

Here is the Windows Defender Firewall's configuration that works for me:

In the LAN Plug-In's settings, check SMB2 and SMB3

Set the Windows Firewall [Private Network]: Active
Open
"Allow Access of App through Firewall" (on the bottom of the "Firewall and Network Protection" window).
On the top right of the new window, select "Change Settings"
Then, check below the column "Private":
-> "File and Printer Sharing" [X]
-> "File and Printer Sharing via SMBDirect" [X]
Exit window with OK on its bottom.

You may wish to finally clear the cache of the Plug-In.

That's odd, why would the firewall let connections through only sometime?

With TC for Android 3.62b2d with Plugin 3.60 on Android 16 and with TC for Android 3.62 with with Plugin 3.60 on Android 14 I still can't connect:

SMB2 AUTH:STATUS_ACCESS_DENIED
(0xc0000022): Authentification failed
for * using com.hieronymous.smbj.auth

The connection on the Android 14 device is unchanged since it was working.
