Good morning all,
Apologies if this isn't the correct forum to raise this issue but I'm unsure of where else to turn.
I'm trying to edit and existing Application Gateway Rule. All I'm trying to do is change the Backend pool setting so that it points at a different backend pool to what I'm currently using.
E.g. at the moment I have a Rule called "MHA-HTTPS-Rule". It's currently pointing at a Backend pool which is simply a couple of IP addresses (10.0.0.4 and 10.0.0.7).
All I want to do is change the rule so that it points at a different IP address.
When I attempt to do this by clicking "Edit" on my rule and changing the Backend pool, I receive this error: There are no http settings with pick host name from backend address set. Create a new http setting with pick host name from backend address set and then try again.
That error makes it sound like I haven't selected the "Pick hostname from backend address" in my associated HTTP settings.
However, when I check the existing settings of the working Rule/Backend pool, that tickbox isn't selected either...
Is this a bug, or am I doing something wrong?
Hi Duncan,
You are missing the HTTP-setting in your Rule.
In the first screenshot where you show your rule there is an empty pulldown where it states "Select an HTTP setting".
From the Application Gateway blade select "HTTP settings" and add a HTTP setting.
Once you have added this HTTP setting you should be able to make the required changes.
Regards,
Daniël
Michel, what does your HTTP setting look like?
When I spoke to Microsoft, they basically said that I needed to tick all of the bottom options (App Service depends on whether or not you're using that - but make sure the others are all ticked):
