ERR_CONNECTION_RESET - unable to reach portal from Internet

Hi, We have 1 arm (no DMZ) setup behind Cisco ASA. Both 80 & 443 has been forwarded to the Internal port. External ports is disabled.

We can reach from the LAN by IP + hostname, however when accessing from the internet, page redirects from http://public-ip to https://public-ip (or hostname) but it says "ERR_CONNECTION_RESET".  

 

I am using Lets encrypt certificate which is selected for the Internal virtual ports. I have also tried with certificate from different supplier and it still throws same error.

 

Not sure what I am missing, any help on this will be much appreciated, thank you.

Re: ERR_CONNECTION_RESET - unable to reach portal from Internet

@bickyz Do you see TCP and SSL handshake happening when connecting from your external machine?

 

Please capture the traffic on the client machine and on the VPN server's Internal port, and check if you see both (TCP + SSL) comms are happening between them. At which point do we see the TCP-RST message being sent? from which device?

 

P.S. do we see any logs on the ASA events regarding the connection attempts?
