Hello! I have a problem with ASA. Our WEB server located in DMZ (behind the ASA). I use static NAT for access from outside. The majority of users have NO problem with access Web server from Internet. But some users (all they use certain Internet Provider (MTS)) can not get access. In ASA log I see this:

4 Aug 22 2016 15:27:35 217.66.152.0 24352 172.16.X.X 80 tcp flow from Outside2:217.X.X.X/24352 to dmz:172.16.X.X/80 terminated by inspection engine, reason - proxy inspector drop reset.

HTTP inspection is disabled.

I do not know what to do. Pleas help!
