No HTTPS request is sent to UE 5.0.3

[DevilRabe]

Good afternoon! Faced with such a problem: I decided to use the plugin to communicate the game with the WEB API on NET Core, decided to make the API over HTTPS to transmit JSON data, and faced with the fact that the plugin seems to be unable to send data to the API over HTTPS and therefore receive them. When I tried over HTTP -> everything worked like a Swiss watch. Please tell me, what could be the problem?
Engine version: 5.0.3 from Epic Launcher
VaRest plugin form Epic Launcher, for UE 5.0

You should set log mode to Verbose for LogHTTP category and check what happens with request. It seemed to be certificate-related issues or something like this.

I think you're right.
