Cluster of 3 IAP's providing employee wireless as well as guest wifi. Guest access is configured to redirect clients to a captive portal page configured on clearpass for radius auth. have this EXACT setup in 5 other branch offices with no issues.. and this has been working for about a year and all of a sudden the clients are not being redirected anymore.. just in this office. IE error page cannot be displayed. The clients are able to manually get to the URL.. I have the IP address configured, so dont think its a DNS issue. they are gettinga valid IP from the DHCP pool. can ping the gateway.. can resolve nslookups.. I have restarted all IAP105's in the cluster.. have restarted the clearpass server. re-entered the shared secret everywhere.. I do see an error in the clearpass system logs regarding one of the AP's in the cluster that is affected. "request failed: error reading the headers"
