I just started with Blynk again after some weeks, my app and esp2866 server still worked fine. Then I noticed the updates to the app, and just updated from the Play Store. Now the app displays “reconnecting to server” all the time, about every second. I becomes pretty much unusable because of that. This is already in the main screen where all the projects are displayed, it has nothing to do with a specific project.
Why is it disconnecting/reconnecting to the Blynk server all the time? This is on a Galaxy S3. Is there a way to downgrade the app so it works again?
I just found the error, I had actually setup a local server and forgot about that. I updated the server, and now I hope it works. Sorry!
However I just tried to use the admin website to change the password for the user on my local server, and I think there may be a real bug there. I changed the password and then clicked ‘save’ at the bottom of the page, but I get a message ‘Oops, an error occured : (code: -1) null’. The log contains the following:
