@sara19 sounds a bit like setting up the connection to the MWS is failing. To check, are you able to login to the TAS portal?

and to make sure we cover the basics, can you confirm that you completed all the steps for HA setups, for example this? https://docs.ifs.com/techdocs/Foundation1/020_installation/400_installation_options/030_touch_apps/010_touch_apps_server/40_installation_tas_web_farm/default.htm

@sara19 do you login to the TAS portal using Local Admin mode? and can you doublecheck the steps you took against the Installation Guide, especially https://docs.ifs.com/techdocs/Foundation1/020_installation/400_installation_options/030_touch_apps/010_touch_apps_server/40_installation_tas_web_farm/default.htm please?

@sara19 I still think how you login to the TAS portal is important. Can you share some screenshots showing how the TAS portal login goes please?

and on Scan It, are you able to login at all?

There are two more things you can try.

  1. Check your web.config and increase the logging level to the highest verbosity. I don’t have an example file at hand to tell you exactly, so please check the web.config, and you might have to search a bit online too
  2. Check if the Windows Event Log has logged any further detail
