e could not able to access the ESR link “http://hostname.com:50000/rep/start/index.jsp” , after patching

hi Experts,

we could not able to access the ESR link “http://hostname.com:50000/rep/start/index.jsp” ,  after patching the below components in XI system 7.11. but other links are working fine.

it throws error:

503   Service Unavailable

  Error: Application cannot be started!

  Details: "The WebApplicationException log ID is [5AF87EF52B06006D0000000A0041004E]."

patched the below components From

SAP_XIESR - 7.11.8.1    to  SAP_XIESR - 7.11.8.16

SAP_XITOOL - 7.11.8.1  to  SAP_XITOOL - 7.11.8.15

SAP_XIAF - 7.11.8.4        to SAP_XIAF - 7.11.8.34

So again later we upgrade the below patch to resolve the issue

SAP_XIGUI - 7.11. 8.1 to SAP_XIGUI - 7.11.8.3.

  But still the same link is not accessible.
