Can't run Web site via https

[wlad_wm]

Hi!
I am trying to run my Web site via HTTPS. Via HTTP everything works fine, but via HTTPS I get error "ERR_SSL_PROTOCOL_ERROR".

I have:
Hardware QNAP D4 Pro, firmware 4.3.6.0895
WebAdmin ports: HTTP-8084 and HTTPS-8081

2 VirtualHost's: for both I defined 80 and 443 ports. Something like that:
SiteA - HTTP - 80
SiteA - HTTPS - 443
SiteB - HTTP - 80
SiteB - HTTPS - 443

I add certificate 'Let's Encrypt' for SiteB.
I tried another certificate from comodo and have the same.

I tried everyting and have error. For example I tried Firefox and get "SSL_ERROR_RX_RECORD_TOO_LONG".

Any ideas?

Sorry. It was a problem in my router. I fix it. Now - all right
