Nick Couchman commented on GUACAMOLE-1283:
------------------------------------------
[~shauntarves]: A couple of things:
1. Please start asking for help on the mailing list:
http://guacamole.apache.org/support/.
2. I doubt this is a bug, particularly in guacd. The ERRINFO_DECRYPT_FAILED
message is upstream from the FreeRDP library, and the "Connection reset by
peer" indicates that the upstream RDP server, or some network device along the
way, is resetting the connection, and not guacd.
3. On the off-chance that it is something guacd-related, please try the latest
version, 1.3.0, and validate that you still have the issue, there.
