Hi Tanuja,
The address for asking Chimera questions is chimera-users at cgl.ucsf.edu, CC'd here.

Probably you were using some tools that call web services: PDB2PQR, APBS, and/or Autodock Vina.  These web services were provided by another group (not our lab) and they have been discontinued, sorry.

There are suggestions of what you could do instead in the help pages for these tools in Chimera:

Probably for APBS and PDB2PQR the simplest approach is to skip Chimera and use the web service at 

If you were trying to do docking, besides the Vina  help link above, there are several posts to the chimera-users list with suggestions of alternatives, for example:

I hope this helps,
