The remote certificate is invalid according to the validation procedure

Hi, We are experiencing issue during AcquireTokenForClient method call.
Certificate seems fine we use similar(not the same. certs are created automatically by terraform for each env) cert on our other environments and did not have any issues.
Below a log of MSIL library which I collected during this call(replaced some data by XXXXXXXXXX just in case):
