Confluence shows only a white page. It seems to automatically log in in the background (showing the login options for a split second before the white page).
Steps taken to solve the problem (all didn't help):
1. login in incognito window
2. login in other browser
3. login from jira overview
4. login from atlassian lading page
5. switching internet connection (added after first answers below)
6. trying different VPN locations (added after first answers below)
Maybe good to know:
- Jira (web) works just fine.
- Both apps on the phone also seem to work.
