http redirect on external websites not working correctly

[markus.bock]

Hello,

I have an asa 5525x cluster on perimter and an asa 5545x as an internal firewall.

I have the problem accessing extenal http websites that should be redirected to https. Most times the error "Website could not be loaded". On a windows client it helps when I reload the page again. But with apple it does not work.

I tested it with http://speigel.de

On asa I cannoot find any errors in log.

WWW---ASA5525X---ASA5545X---LAN

Can anybody help me please

is this Simple firewall both, or any SFR involved like IPS / content inspection?

try website press F12 and click network while accessing the web site.

are you able to nslookup with that site from PC ? , what if you type directly https://www.spiegel.de/

Sorry. Yes, SFR is active but in FMC I cannot find any BLOCK entries. 

DNS is working without problems

I fw logs I can see access to the website on tcp 80. And when I reload the site on windows client I can see access to the website with tcp 443
