Solution
The secret is in the callback not trebuetsa https. Can safely raise http and in community settings to specify the ip instead of the domain.
hmm I'll try it now but mine is even seen in the news group that they completely switched to https - christian35 commented on June 27th 19 at 15:06
requests can be done only via https, to create iframe app only from https. Colback for nothing. - terrell_Satterfield commented on June 27th 19 at 15:09
: That is so I can get a notification to the server about the fact that someone wrote the message, but back to answer the customer who wrote it I can't do this without https? - christian35 commented on June 27th 19 at 15:12
: stupid. Here You are with your computer you can go to https sites? But for that You register any certificate? Here your server acts as the exactly the same as You client for outbound requests, just in response, he receives not render the pages and json data (well, of course, and may page to...) - terrell_Satterfield commented on June 27th 19 at 15:15
