Can not surf to a website

Hi

when trying to surf to a specific website i get this error "ERR_EMPTY_RESPONSE" on all browsers.

When I open the same website from a private PC (no firewall) then it works with no problem.

 

All logs are "Accept" but still getting "ERR_EMPTY_RESPONSE" on browsers

 

What should I troubleshoot when seeing this: ERR_EMPTY_RESPONSE  ?

Can you share what site? Is there ssl inspection involved?

Just tried both in lab with ssl inspection and without and worked fine. Can you confirm what this is set to now? Not sure if you changed it or not...

K, fair enough. Did you make custom category to allow the sites?

I did not tested to add it there!

Should I add it as an IP address or as FQDN like *.matematikxyz.com ?

If you filter logs for that destination IP, just do nslookup, make sure it resolved to same IP, what do you see?

One thing I found super useful with these issues is press F12 when going to the site, so it gives you developer browser tool, it may show you if its trying to reach something else as well.

Let's start with basic information like: Version and JHF level of gateway and maangement.
The exact rules used to allow the traffic (with custom service definitions shown).
What shows in the access logs when you attempt to access these sites (full log card, not just the line in the logs list).

Please provide screenshots where appropriate and redact sensitive details.

I found this interesting thing on the log:

That sk is essentially long way of telling you 3 way handshake is not completing...so doing fw monitor with -F flag would probably help.

If the Access Rulebase does not reach a final match on accept, a log appears with a new unique rule specific for this case 'CPNotEnoughDataForRuleMatch' and accept action. !

Lets assume your PC ip is 10.10.10.10

Idea is this fw monitor -F "srcip,srcport,dstip,dstport,protocol" -F "other way around"

example:

fw monitor -F "10.10.10.10,0,208.86.159.100,443,0" -F "208.86.159.100,0,10.10.10.10,443,0"

As you can see, I left src port and protocol as 0

Just replace 10.10.10.10 with your actual internal IP

Can you run zdebug for that IP?

fw ctl zdebug + drop | grep 208.86.159.100

Seems nothing comes back at all.

ip r g 208.86.159.100

fw monitor -e "accept host(208.86.159.100);"

Run them while testing.

If still no good indication, I would work with TAC to see whay this fails. Its entirely possible it might not even be fw issue at all.
