Cwa-documentation: URL/URI, Ports for firewall whitelists

[gizmo21]

Is there any documentation about which URLs/Ports a firewall (BLOKADA, PI-hole...) should not block to use the app?
I found some in sources, but perhaps there are more:

SUBMISSION_CDN_URL=https://submission.coronawarn.app
DOWNLOAD_CDN_URL=https://svc90.main.px.t-online.de
VERIFICATION_CDN_URL=https://verification.coronawarn.app

This could help to locate problems.

These are the only URLs we use inside the active code, so the domain *.coronawarn.app and *.t-online.de whitelisted should be enough to ensure communication for the App. I will bring it up with the team to check wether it makes sense to explicitly document it, however it is unlikely to be a benefit for most people imo.

Well if not many private have use for it, perhaps work environments could help it.

We moved this issue since it affects general documentation of the project, not only the android app.

This thread will be closed since the question has been answered by @jakobmoellersap. If there is a need to continue the discussion, it will be reopened.

Hello @gizmo21 ,

I will reopen the issue due to your idea to document the URLs somewhere for the community.
this I will discuss internally.

thanks,
