VDI not working after connection server upgraded to 7.7

Hello,

 

We have a VDI solution in our environment. The connection server was earlier on 7.1. It was upgraded to 7.7 and since then vdi solution doesnt work.

 

It logs following errors in the apm logs:

 

Error while trying to handle webtop request: SessionDB

 

When searched for the above message, it asked us to create an irule which is already in environment

 

The irule is following:

 

when HTTP_REQUEST { if { [HTTP::header "Origin"] ne "" } { HTTP::header remove "Origin" } }

 

We have enabled debugging on VDi and got following logs in apm

 

{148.C} <- HttpResponse[HTTP/1.1 500 Internal Server Error] Dec 30 16:05:54 st-lbzq01 debug vdi[16692]: 019cffff:7: /Citrix/vdi-qa.app/vdi-qa_apm_access:Citrix:4311e47d: {148.C} BHL_OnCall: Got HttpResponse[HTTP/1.1 500 Internal Server Error] Dec 30 16:05:54 XXXXX debug vdi[16692]: 019cffff:7: /Citrix/vdi-qa.app/vdi-qa_apm_access:Citrix:4311e47d: {148.C} <- HttpHeaders[3] Dec 30 16:05:54 st-lbzq01 debug vdi[16692]: 019cffff:7: /Citrix/vdi-qa.app/vdi-qa_apm_access:Citrix:4311e47d: {148.C} ConnectionClose=0 Dec 30 16:05:54 st-lbzq01 debug vdi[16692]: 019cffff:7: /Citrix/vdi-qa.app/vdi-qa_apm_access:Citrix:4311e47d: {148.C} BHL_OnCall: Got HttpHeaders[3]

 

Please advise if any solution is available.
