@vshymanskyy does library supports :8080 port part of request uri?

[vshymanskyy]

it should support specifying port - but to verify it, we need to test a case with local server, with default port.

[vshymanskyy]

Basically, back that time when it was not supported by the server, i was performing OTA from local machine (and non-default port), and it worked perfectly. Most probably it's not a bug.

@Refenz what is IP address of the device itself?

[vshymanskyy]

@Refenz is issue resolved?

[Refenz]

@vshymanskyy Yes. All is fine. Thanks!
