EmonESP w/ Multiple Browser Windows - Probable cause?

Tags: #<Tag:0x00007fc9b23b6bd0>

Yesterday I had one heck of a time with EmonESP. It was great and I was thrilled. But, then at one point it stopped working. I couldn’t pull up the web interface. It just kept loading and never responded.

I flashed another EmonESP and it worked great. Sometimes.

Late last night, I read through some development discussions between Glyn and Jeremy. I can’t find it now, but one mentioned he had issues with multiple browser windows open and the ESP hanging.

So, this morning I found that I did indeed have the first EmonESP pulled up in another tab in another Chrome window. I closed that and things have been running great!

So far today, with only having 1 admin window open, both ESPs are running perfectly.

How feasible is it that this is my issue? Is this something that would make sense to be the problem?

The default web server library (that EmonESP is using) only supports a single connection so if you have two or more admin windows open I think they end up clashing, possibly when also combined with updating EmonCMS and/or MQTT.
