Blazor WASM net::ERR_HTTP2_PROTOCOL_ERROR
Is there an existing issue for this?
- [X] I have searched the existing issues
Describe the bug
I have a Blazor wasm site: https://ims.kfacon.com. When I load it first time, I get this error in console: net::ERR_HTTP2_PROTOCOL_ERROR on several files.
However, when I refresh the same browser, everything runs smooth and site loads.
Expected Behavior
Site should load without the net::ERR_HTTP2_PROTOCOL_ERROR.
Steps To Reproduce
Open Edge browser and navigate to https://ims.kfacon.com If this is the first time, you will get the error. If you will refresh, the error will go away. If you will open in InPrivate windows, you will see the error again.
The behavior is consistent in Edge and Chrome. It does not occur in Firefox.
Exceptions (if any)
Does not happen in Firefox.
.NET Version
.NET 7

This seems like some type of issue with your network. Can you give us more details about your deployment? As well as any other software that you might have between your machine and the server? (Enterprise proxy, web application firewall, etc.)

The site is hosted on Digital Ocean and is served via Nginx server. There is no proxy, firewall etc. between the client and the site. You can experience yourself by clicking on the site link. I need to dig further to get a Wireshark trace.
Can you capture a decrypted wireshark trace?
Where do you want me to load the trace?
@dajma00 can you try to share the compressed trace here as an attachment in a comment?

Trace.

@dajma00 you'll also need to include the keys file: https://resources.infosecinstitute.com/topic/decrypting-ssl-tls-traffic-with-wireshark/
