FAQ: Error 2001 missing link to firewall settings
See original GitHub issueWhere to find the issue
- https://www.coronawarn.app/en/faq/#cause2001 “[Google/Android]: CAUSE: 2001, trying to establish a secure connection to the server”
- https://www.coronawarn.app/de/faq/#cause2001 “[Google/Android]: URSACHE: 2001, trying to establish a secure connection to the server”
Describe the issue
The FAQ article #cause2001 does not mention that firewall settings may also contribute to the error message “CAUSE: 2001” appearing.
Suggested change
Add a troubleshooting step to #cause2001 in addition to checking for certificates enabled which refers to firewall settings and links to the corresponding firewall article #access-list for both languages.

Background information
In https://github.com/corona-warn-app/cwa-app-android/issues/968#issuecomment-907159657 and previous posts in that thread user @Goliath0 reported that certificates were active and there was still a problem with error message 2001. On the advice of @vaubaehn the user wrote that they allowed access to svc80.main.px.t-online.de (sic) and @Goliath0 confirmed in https://github.com/corona-warn-app/cwa-app-android/issues/968#issuecomment-907164158 that this solved the issue.
Edit: Note that the app does not use svc80.main.px.t-online.de
https://github.com/corona-warn-app/cwa-app-android/blob/main/prod_environments.json defines
"DOWNLOAD_CDN_URL": "https://svc90.main.px.t-online.de",
so we assume the user intended to write https://svc90.main.px.t-online.de.

@vaubaehn
Thanks for pointing out the typo! The PR does not specifically mention this node name, only
*.t-online.dethrough the reference to https://www.coronawarn.app/en/faq/#access-list. I edited the original entry above to highlight the typo so nobody is misled, trying to use the wrong node name.PR https://github.com/corona-warn-app/cwa-website/pull/1681 is merged, which resolves this issue.
