Error: net::ERR_HTTP2_PROTOCOL_ERROR

Customer10219

Hi, I'm having a problem with a specific endpoint. For some reason, it's returning the error: net::ERR_HTTP2_PROTOCOL_ERROR.
Suddenly, the endpoint started failing, throwing this error.
It works locally, but not remotely.
I'm using Angular with the .NET 9 Web API. The backend is hosted on their servers.

Hello @Customer10219,
thank you for using our hosting services.

Error: net::ERR_HTTP2_PROTOCOL_ERROR

Means that HTTPS communication did not complete successfully. In other words your application suddenly stopped responding during HTTPS communication with your visitor internet browser. This is usually caused by one of following two reasons:

1) Your application is exceeding memory limit:
You can check this in our Control panel. Look for messages on Logs tab and check Resources graphs as well:

2) Your application is crashing unexpectedly.
This may be due to unhandled exceptions in your code. Please follow this guide to enable debug logging and find out what’s causing this problem:

Hello again.

There's a problem with your servers, as far as I understand.

First of all, the logs show me these errors:

A process serving application pool 'site29092' exceeded time limits during shut down. The process id was '26360'.
A worker process serving application pool 'site29092' has requested a recycle because it reached its private bytes memory limit.

When the endpoint is executed and the query is processed using LINQ, the tables or the database appear to be unresponsive.

When I access the database from the Admin view in MonsterASP and select the Admin option, some tables allow me to access, but in others, like News, Cloudflare gives me a timeout because webmssql.monsterasp.net is unresponsive.

The News table doesn't have much content, only 10 records.
On the other hand, this only happens with one specific endpoint, while other endpoints that also use the News table work correctly.
