Since yesterday my Web App (linux) deployments from Visual Studio all fail with a generic error "The server experienced an issue processing the request.". No more details in the log or output console. VSCode ZIP deployment works fine
If I visit the publishing target url (https://waws-prod-am2-351.publish.azurewebsites.windows.net/) in the browser, I get a ERR_HTTP2_INADEQUATE_TRANSPORT_SECURITY error. SSLLabs.com's server checker also gives a score that indicates configuration problems (server negotiated HTTP/2 with blacklisted suite). Visiting the site in Internet Explorer or in Firefox with HTTP/2 disabled gives a 404 on the root (probably expected when you visit the url manually).
I expect this is the root cause. Is this a known issue? Does it affect multiple app service plan instances? Is there a work around other than disable HTTP/2 on my whole machine?
