I’m running the latest local server (0.29.6) and it seems like each time I update the server (possibly since 0.29.2/3/4) I have had to sign out of devices that I have shared access with, generate a new QR code and use that to log in.
The “main” app is fine but the “shared” app just hangs with the three green dots spinning on login. I have tested this with both Android and iOS clients with the same outcome.
Probably by design if you think about it.
Then it’s a new “feature” because that wasn’t how it worked until relatively recently.
So apps just do not reconnect? And apps are running all the time?
Nope? I’ve never had a need to do that.
I kill the process on the server and spin up the new version.
Good that’s right.
@ThatGuy_ZA could you please enable debug mode on server and post here your logs for that case?
Is issue reproduced when you restart server (without upgrade)?
I restarted the server several times (in the same way I do when I upgrade it) and no issues with sharing.
Here is the log file for a restart.

So all is fine 
?
@Dmitriy Nope, the issue is present when upgrading the server.
I’ll do the next upgrade with debugging enabled.
Very strange. There was 1 version with sharing changes, but it shouldn’t affect sharing in any way. Seems to me like some local env. issue. Anyway, forever endless spinning dots is a bug and we will fix it. Do you have shared app on both iOs and Andorid?
I don’t think it is a local environment issue because nothing else has changed.
Yes, shared app is on both Android and iOS and I experience the same spinning dots on both.
Could you send us in PM the QR for the shared project that is not loading now, so we could debug this issue on our side?
@Dmitriy is it possible that share credentials could become invalid after server’s upgrade?
Android Phone App. not logging into local server using SHARED QR code
Running latest versions:
Note: I even tried regenerating another QR but no difference.
Observations:
@BlynkAndroidDev - This seems to imply that on the Android, its not even reaching the local server.
Have you clicked refresh button on the Share screen? Support for old share QRs would be fixed in the next release.
