it im getting
following errors

X11TransSocketOpen: socket() failed for tcp
_X11TransSocketOpenCOTSClient: Unable to open socket for tcp
_X11TransOpen: transport open failed for tcp/145.49.0.179:0
Error: Can't open display: 145.49.0.179:0.0

and some times 

X Error of failed request:  BadGC (invalid GC parameter)
  Major opcode of failed request:  60 (X_FreeGC)
  Resource id in failed request:  0x1000007
  Serial number of failed request:  108
