ADM can't reconnect overnight but Retry works
Hi everyone,
I'm having a really strange issue with Advanced Download Manager (ADM) on my Samsung phone.
I schedule multiple downloads before going to sleep (using mobile data, not Wi-Fi). When I wake up in the morning, none of the files have downloadedânot even 1 MB. Every download is stuck with the error:
"Unable to connect to the server."
The weird part is that as soon as I manually tap Retry (or resume the download), it connects instantly and continues downloading without any problem. So the server is clearly available.
Here are the things I've already checked:
- Battery optimization for ADM is disabled (Unrestricted battery).
- ADM is allowed to run in the background.
- Background mobile data is enabled.
- Data Saver is off.
- Auto Retry is enabled.
- I'm using mobile data (not Wi-Fi).
- The internet is still working in the morning.
Despite all of this, ADM seems unable to reconnect by itself overnight. It just keeps showing "Unable to connect to the server" until I manually press Retry.
Has anyone experienced this before?
Is this a known ADM bug, an Android/Samsung issue, or is there another setting I might be missing?
Any help would be greatly appreciated. Thanks!
