Time was lost during call-in for 1L10 circuit breaker trip due to a 504 Gateway time out error. Two locations were tried. First from the Fishbowl Windows machine, then my Cube in building 55. Both locations produced the same error. Finally had to access EPAS from the MCC Redhat machine with help from the Crew Chief on duty because I was not familiar with the Redhat operating system S.
