URL citrix.rsieh.com is inaccessible through firewall

ChandrashekharD — Wed, 25 Feb 2026 16:21:20 GMT

Hi Friends,

1) One of my customer is trying to access https://citrix.rsieh.com, although it initially opened, and it was soon redirected to https://sso-fe2eb653.sso.duosecurity.com/saml2/sp/sso and site is getting inaccessible through firewall

2) This are the User-Id users and they are not using authentication and decryption policy and apart from this URL, all other websites are working fine under the same security policy only this particular URL is not accessible.

3) We also tried allowing, DNS Name: *.login.duosecurity.com , *.sso.duosecurity.com but no luck

Kindly help me with the next step

Model:- PA-440
PANOS:- 11.1.6-h10

Regards,

Chandrashekhar

@ChandrashekharD,

This is almost certainly that your existing policy just doesn't match for the traffic and it's getting dropped. You can validate if traffic is getting dropped by either building a targeted policy at the bottom of your rulebase, or simply enable logging on your interzone-default policy.

You'll likely need to take a test user and build them out a policy that isn't locked down and ensure that you use the alert-all URL profile assigned to match what they're actually hitting. It is likely that you aren't allowing the identified application or a required domain to actually allow things to function.
