Schannel Event ID 36887 Error

[Mr Wolf]

Hi all!
I noticed two errors in my Event Viewer regarding Schannel with Event ID 36887, one with error:
Fatal alert received: 40
and the other one with error:
Fatal alert received: 70

After some investigations, I discovered they seem related to Gimp: I get those errors whenever I start Gimp, but, oddly enough, in the computer in which I noticed them first, I also get them at boot.

I'm running Gimp 2.10.22 on Windows 7 64 bit.

I also tried to install Gimp 2.10.22 on another machine with Windows 7 64 bit and I get the same error, but only with code 40 and only when I start Gimp, but not at boot.

I don't have the same errors on a machine with Windows 10 64 bit.

I made some searches, but I haven't well understood the meaning of those errors. Perhaps Gimp is trying to connect to some server to find updates?

Did anyone notice those errors, too?

Thanks in advance.
