We're seeing the same errors pretty consistently. The resource changes each time, but it's always on the resources' Application Insights. So far, just retrying the plan (multiple times in some cases) seems to eventually get it through, but that's getting untenable.

Hi @omkaracharya17 , thanks for submitting the issue!

The mentioned used provider version is 2.99.0 which releases year ago (not sure if you type the wrong version), and recent code change for azurerm_application_gateway was 3 months ago, no code change is made recently.

The 504 error might be something wrong at Azure side. And to help investigation, could you please help provide debug log which contain HTTP request trace?

[pdefreitas]

Same behavior on 3.95 sometimes the plan works, sometimes it gives a timeout. It seems to be Azure related.

[JRobertEdwards]

Also seeing this behaviour pretty consistently as outlined in this ticket #27267

Assume there's no resolution yet outside of brute forcing it over multiple tries

[vivaladan]

I also see this intermittently and have to re-run the plan. Usually one more try will do it.

It might be helpful to remove the v/2.x (legacy) label, as this is happening with 3.x and 4.x versions as well.
