Additional Information

Recently I did a clean flesh install of my Poco F3 (Xiaomi) and I'm running only a few apps as Google Drive, Google Authenticator, WhatsApp over Android 13 (MIUI 14) and all apps that are Google Backup Sync dependent stuck when accessing Cloud (upload/download). I didn't noticed any blocking event in the AdGuard - Recent Activity (only some few blocked ads) that could justify this behaviour or identify the app that had been filtered/blocked by AdGuard and there is no obvious way to add in the allowlist filter. That´s a huge issue once to do backup/restore/sync data it's mandatory to disable AdGuard. How can we handle it? Let me know if other inputs are needed to fix it or even if you know some workaround. Thanks in advance,

Did you receive the log file?

@Birraque Yes, we are examining your logs. If you try to reproduce this same issue using the Local VPN operating mode, would it be the case then?

The Reported Bug only happens when Automatic Proxy (root Mode) selected.

@Birraque Hi! We managed to reproduce this issue on our side. We will find a way to fix this bug in the future versions.

Please use Local VPN operating mode as a temporary solution.

Not a workaround for me. I rooted the device to use AdGuard. I need the VPN for corporate use.

I just created ticket #832674 through the app's bug reporting function. Other apps are impacted, eg. Discord, 9gag, Spark...

I totally agree with you. Almost all apps and system been impacted when Proxy "root" selected. The only functional workaround for me was to disable AdGuard for...

• Google Play Services (com.google.android.gms)
• All Bank apps
• All Backup apps
• All Cloud Storage Sync apps (Google Drive, OneDrive)
• All Authenticator apps (Google, Microsoft)
• All Email apps
• All Calendar apps
• All Contact apps

And still counting... That's unacceptable AdGuard hadn't address it yet.

Automatic Proxy has been mostly working so far, except for Microsoft services or websites, where it fails outright until I deactivate protection. None of the affected apps show the domains being blocked.

I'm guessing Automatic proxy is very complex to maintain.

EDIT: I was wrong. It's also affecting VPN mode. I can't use Microsoft services at all with protection on. I might send logs.

I mostly use Microsoft services for work (aside from Authenticator, which I plan to get away from); having no access with protection enabled means I won't receive any notification from Live or Azure domains.
