timesheet tracking page is not opening for me .
112bm61-humvfd6k5-2m4m8bqfmu--k77xng-1mhketb5b0-1qcfkx1xko.cdn.prod.atlassian-dev.net’s server IP address could not be found.

Hi @Piyush Gupta, that host isn't the vendor's. cdn.prod.atlassian-dev.net is Atlassian's own domain, where Forge app UIs get served from, and Atlassian's allowlist page lists atlassian-dev.net (wildcarded) with the note "Marketplace and custom apps use this". Nothing for the app team to fix there.

"Server IP address could not be found" is DNS failing before any request reaches the app. Try the same Jira page on a phone hotspot. If the timesheet panel renders, it's your network, and whoever runs your DNS or web filter has to allow that domain. While it's blocked every Forge app on the site goes blank the same way, so that's what to take to IT.

HI @Piyush Gupta 

As this is 3rd party integration, contact the app support department.

As this error is specific related to the app "Timesheet Tracking for Jira".

Hello @Piyush Gupta 

Atlassian describes this exact “server IP address could not be found” error as occurring with some corporate VPNs or DNS systems that reject the dynamically generated Forge hostnames or mishandle their short DNS TTL.

[ECO-663] When using a Forge app on certain networks the app shows a error page that says it might be temporarily down or it may have moved permanently to a new web address. - Create and track feature requests for Atlassian products.

Well, already looking on your screenshot shows pretty classic network-related problem.

Troubleshooting should be Started from Network side.

Best,

Arek🤠
