[game] Galaxy auth failure: FAILURE_REASON_CONNECTION_FAILURE | help (помогите)

[Ostensibility]

Good time of day.

Not so long ago, I bought Stardew Valley and played for a while without any problems. Then I installed SMAPI and there were no problems either, but yesterday when I decided to play, I ran into this problem: when walking around the location, I get a "trigger" strip that distorts the image, it is small but noticeable. I tried to capture it in a screenshot, but it's not visible. In multiplayer, I have this strip in the same way, but I get thrown off the farm after a while.

I must say right away - at the moment I have Windows 7 Max, in the coming months I planned to change my computer and update Windows, but at the moment this does not prevent me from using the device.

In the SMAPI log, the problem is written as:
[game] Galaxy auth failure: FAILURE_REASON_CONNECTION_FAILURE
I tried to find a solution to the problem on the Internet, but I didn't find much and the ways I found didn't help me.

What was I trying to do:
I deleted SMAPI and mods, installed the previous version of SMAPI, rebooted the computer, the router (by the way, I have no problems with the Internet, everything else works fine, but there is no multiplayer in stardew) reinstalled the game with its complete removal, turned off the firewall.

!That is, the game does not work normally even without mods and SMAPI!

I am not a master of computers and some solutions to problems, let's say like here: https://www.reddit.com/r/SMAPI/comments/1bmsxla/multiplayer_no_longer_works_after_16_update_and_i/
I don't quite understand, and the conclusion I came to from this post is to disable the firewall, because I can't do anything else and couldn't find a solution on the Internet.
None of this helped...
unfortunately, it's impossible to have fun playing the game together
If you can help with solving the problem, I will be eternally grateful to you!! Also, if you need the full SMAPI log, I can send it to you.
I do not know where else to turn :(((
thank you in advance.
