Mike Jumper commented on GUACAMOLE-1240:
----------------------------------------
The error shown above ("ERRINFO_DECRYPT_FAILED") is an internal error within
FreeRDP related to decrypting the traffic from the RDP server. That combined
with the error related to {{BIO_read}} that follows (which would be from
OpenSSL), this really looks more like an issue either within the RDP server or
within FreeRDP itself. The components that are failing here are well below the
level at which Guacamole is operating.
