Connection closes after 20 seconds on SoftEther server

Post by ekinyuksel12 »

I can connect to that server over my windows and Linux machine with no problem and connection stays on. But with this app it cannot sustains the connection after 20 seconds. It gives "B00C60ED76000000:error:0A000126:SSL routines:ssl3_read_n:unexpected eof while reading:ssl/record/rec_layer_s3.c:309" erorr before it closes. Here's the log of the whole connection the error happens at "2022-06-15 14:25:56".

Hello,

I tried to reproduce the problem but everything seems to work fine on my devices.
Perhaps the problem is related to the new OpenSSL 3.0.3 library.
I sent you a private message with the previous version to try.
