WAF v2 and use of Lets Encrypt wildcard
Hello All, I´m using WAF v2 and one of my listeners uses Port 443 and multi-site domain. I´ve generated a SSL WildCard for this domain using Let´s Encrypt. When I put WAF in front of this specific site/domain, I receive an error as following The connection for this site is not secure homolog-icg.icgti.com.br uses an unsupported protocol ERR_SSL_VERSION_OR_CIPHER_MISMATCH. My SSL Policy is as following: Min protocol version TLSv1_2 Cipher suites TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 TLS_DHE_RSA_WITH_AES_128_GCM_SHA256 I have other websites with other SSL WildCard certificate (paid-not free) in the same backend pool but a different Listener and the error doesn´t happen with them also. I would suspect that could be the SSL configuration in the server machine, but if other websites are working fine, my guess should be the certificate that not allow the type of cyphers I have in my SSL Policy. Is this make any sense? Anyone have tried something similar scenario? Thanks Mirella

Azure Firewall Manager
I'm looking for confirmation as to whether my suspicions are correct or I'm a complete idiot. If I'm using AFM and it is deployed in West US, for example, am I able to modify policies in the event there is some kind of Azure outage in the West US region (let's just pretend complete outage for the sake of the conversation)? I'm assuming a managed service like AFM is set up with native HA/failover and would not be impacted by something like this...is that wrong of me?

Logic app search replace function usage example?
Can someone please give me an example function for search and replace? I'm using html in the sentinel 'add comments' operator and I'm seeing lots of \n characters. I want to remove them all so they don't write line feeds to the output and mess up my html markup. Thank you.
