Any relevant info from hotspot logs?
Device can also be asked to log SDK routines; set dbgSDK 1 and reset in console and see additional serial output

After a while it seems to connect, but I don't have access to the Webui, nor does it respond to ping. This ip that appears in the log is not what I configured

Hi,

It is working now. I discovered that it is necessary to configure the "DNS IP" in this version. In version 1.14.1 it is not necessary (I have five devices configured like this).

thanks !

This line has to be removed then

espurna/code/espurna/wifi.cpp

Line 767 in d86be56

&& _dns.isSet();

If you think this should work regardless of DNS setting

espurna/code/espurna/wifi.cpp

Line 1475 in d86be56

dns_setserver(0, ipsettings.dns());

(afaik IPAddress{} default is 0.0.0.0, so everything else should work)
