Hi, I've got the very same issue.

System Android Version: 14 Custom ROM: /e/ OS 2.19

microG microG Core version: 0.3.6.244735-dirty

[benwaffle]

i was able to sign up now

[rockstorm101]

I'm still unable to log in.

System Android Version: 14 Custom ROM: /e/OS 3.0.1

microG microG Core version: 0.3.6.244735-17

I can't sign up too. Error identical as in the opening post. when it asks for my email, I put it in, but clicking Next does nothing.

System FairPhone 4 5G bought from murena. Android Version: 14 Custom ROM: /e/OS 3.0.2 official

microG microG Core version: 0.3.6.244735-17 Self-Check: all good.

You all are 3 versions of microG behind, you can't expect to see a fix if you don't update microG :-)

Well, apparently I am unable to independently upgrade microG on /e/ OS, as it comes bundled with the official ROM upgrade. As I am running the latest version /e/OS released by Murena a couple of months ago, I am truly not sure what else can I do? Apart from requesting re-opening this issue :-))) https://community.e.foundation/t/is-possible-to-upgrade-microg/46947/2

OK, I managed to upgrade my /e/ OS to 3.0.4 from official Murena source. Alas, this version also contains microG 0.3.6.244735-17(049740c) I double-checked if that resolved the problem - alas not - it's exactly the same, doing nothing on "Next" button click

Admin - please re-open the issue.

@Appo77 You need to update microG to v0.3.9 (or wait the ROM to update it). microG cannot do anything if the ROM maintainers do not update it.

Same problem in a Motorola G34 5G with last LineageOS 22.2 ROM (Android 15) and microG v0.3.9.250932 (25/7/2025) installed.

If you can get a logcat with microG v0.3.9 it would be very helpful.

Sure:

adb logcat -c && adb logcat -v time | tee full_log.log | grep -i -E "GmsCore|GsfProxy|io\.yuka\.android" > yuka_microg.log

See zip file attached with both log files.
