Executing "mono ./tlstest.exe https://qa.4act.com:5151 --web --ssl" using mono 4.6 (Stable 126.96.36.199/abb06f1 Wed Sep 28 13:54:26 UTC 2016) will output "Error #-2146762481: CERT_E_CN_NO_MATCH 0x800B010F."
If I execute the same command using 4.4, it works successfully. If I execute the same command using the same server and same certificates but on a standard port, it works successfully.
If I use --tls instead of --ssl, I get the same error and a response of 400 bad request. In my apache error log, I see the following error.
[Thu Oct 06 09:12:53.506079 2016] [ssl:error] [pid 28950] AH02032: Hostname qa.4act.com:5151 provided via SNI and hostname qa.4act.com provided via HTTP are different
I am having this issue within my development network after upgrading 4.6.0 and beyond. I tried many things with the format of the certs w/o success. Following this information, I tried running on port 443 and it no longer throws the error.
I am experiencing this issue as well.
Any attempts to connect to an Apache2 server, using HTTPS (SSL), and the non standard port number (443) Results in the following exception being thrown..
System.Net.WebException: The remote server returned an error: (400) Bad Request.
Apache2 Logs show the following error
AH02032: Hostname weather.mywebserver.com.au:8081 provided via SNI and hostname weather.01solutions.com.au provided via HTTP are different
Problem can be replicated using HttpWebRequest, WebClient, and HttpClient
Here is a dump of the URI used to send the request
AbsolutePath = /xml
AbsoluteUri = https://weather.01solutions.com.au:8081/xml
Authority = weather.01solutions.com.au:8081
DnsSafeHost = weather.01solutions.com.au
Host = weather.01solutions.com.au
HostNameType = Dns
IsAbsoluteUri = True
IsDefaultPort = False
IsFile = False
IsLoopback = False
IsUnc = False
LocalPath = /xml/users/login
OriginalString = https://weather.01solutions.com.au:8081/xml/users/login
PathAndQuery = /xml/users/login
Port = 8081
Scheme = https
Segments = /,xml
UserEscaped = False
My thinking is setting the Host name to include the port would fix this issue up.
This was fixed in the recent C8SR2 release (Mono 188.8.131.52):
