tcp_connect: can only connect from state CLOSED

[FredrikFornstad]

Andy,
I am not sure this issue is due to lws-esp32-factory or if it is an esp-idf problem (or a combination...). However, I only see this in the lws-esp32-factory app, not in the lws-esp32-test-demos. Nor did I see this back in end of April with the versions of lws or esp-idf that I was using then.

After flashing the factory app, everything works as expected. I connect to the esp32 wifi AP and surf to 192.168.4.1 from a web browser. Still working. Then I configure the 1st wifi slot with my wifi router credentials and save. Still no issue. But immediately when I connect to the esp32 via the router I start to get (an esp-idf error?)
"tcp_connect: can only connect from state CLOSED".
After a short period the web page in the browser goes "dimmed" with the spinning Icon on top. Refreshing the webpage gets it back for a while, then it gets dimmed again, etc. Short after (1-3 seconds) after each tcp_connect error I also get a notice:
?[35;1m[2018/08/19 18:15:47:8582] NOTICE: Client connection error server's cert didn't look good, X509_V_ERR = 24: CA is not trusted

While the factory app is not totally broken (I need to keep doing refresh every now and then) it still feels like something should be fixed. I am happy trying to help, but I do not know where I should look next. Any ideas?
