For the past month I’ve been getting the following error
502 – Web server received an invalid response while acting as a gateway or proxy server.There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server.
I searched the internet – all to no avail – I tried Stack Overflow – no luck.
However, when I tried on the Azure Forums, they suggested turning on Failed Request tracing – which I did.
And while the error logs did not reveal any helpful error information, like “Setting A is set to true when it should be set to false for this to work” it did list quite a few entries for Glimpse – which I was using for my main website (the blog is in a subdirectory). On a hunch I turned that off, and presto! The site is working like a charm. Why Glimpse when the site is deployed I have no idea, but I’m thrilled to not have the error anymore.
