intermittant webpages unavailable usoing 443 on ASA 5515

[mburguk1000]

I have an intermittent issue with web traffic using 443 through ASA 5515 where the issue is web site unavailable and other generic errors

It has only happened since we installed new firewalls ASA 5515 and when I look at logs within ASDM I can see some errors which I think are related to the issue and it says

35595 199.96.57.8 443 Deny TCP (no connection) from 10.0.36.244/35595 to 199.96.57.8/443 flags RST  on interface inside

What makes it harder these errors are random

Any help would be greatly appreciated

Thank you

Hi,

These errors that you have pointed out might not be directly related to the issue.

Are we using any modules on the ASA 5515 device for this traffic to be inspected ?

Also , I think you might need to verify the issue with different browser and verifying the connectivity for the DNS server as well.

Thanks and Regards,
