[PM-40081] Fails to connect to server to update, sync, etc. with Cloudflare Zero Trust protection enabled

[robinsonkw]

Steps To Reproduce

System

1. Android device
2. Cloudflare Zero Trust protection profile enabled
3. Open Bitwarden
4. Get an error occurred.

Vault unlocks and can be used for stored passwords, but cannot update passwords, save new ones, etc.

Expected Result

App works like normal including syncing and saving new items or updates.

Actual Result

App provides "an error occurred"

Desktop
Both the desktop version Bitwarden (MacOS) and website at vault.bitwarden.com work normally when Cloudflare is enabled

Screenshots or Videos

No response

Additional Context

I ran flight recorder with Cloudflare on and tried to sync the vault and start a new login type. Then, I turned off Cloudflare and ran the same actions.

Issue Tracking Info

• I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.
