What's the net::ERR_HTTP2_PROTOCOL_ERROR about ?

[Tristan Gierczynski]

Hi everyone,

I'm not sure where to post this so I'll give it a try here.

I'm currently working on a website, which triggers me a net::ERR_HTTP2_PROTOCOL_ERROR 200 error on Google Chrome. I'm not sure exactly what can provoque this error, I just noticed it pops out only when accessing the website in HTTPS. I can't be 100% sure it is related, but it looks like it prevents javascript to be executed properly.

For instance, the following scenario happens :

1. I'm accessing the website in HTTPS

2. My Twitter feed integrated via https://publish.twitter.com  isn't loaded at all 

3. I can notice in console the ERR_HTTP2_PROTOCOL_ERROR

4. If I remove the code to load the Twitter feed, the error remains

5. If I access the website in HTTP, the Twitter feed appears and the error disappear 

Google Chrome is the only web browser triggering the error : it works well on both IE and Firefox.
(NB : I tried with Safari, and I have a similar kcferrordomaincfnetwork 303 error)
I was wondering if it could be related to the header returned by the server, since there is this '200' mention in the error, and a 404 / 500 isn't triggering the error. 

Thing is the error isn't documented at all. Google search gives me a very few results. Moreover, I noticed it appears on very recent Google Chrome releases ; the error doesn't pop on v.64.X, but it does on v.75+ (regardless of the OS ; I'm working on Mac tho).

Any clue at this point to investigate would be gladly appreciated !
Thanks in advance.

Tristan

This sounds like an issue with your http server. If you capture a
netlog dump (instructions at
https://dev.chromium.org/for-testers/providing-network-details), that
might provide more detail in debugging what's going on.

Hi,

I'm also facing similar issue on chrome, our angular 6 app run successfully but we face this "err_http2_protocol_error" issue intermittently.  We observed when this error occurred calls to our APIs are also failed. 

can someone please help me to resolve this.

Please see the previous message from Nick

To re-iterate:

There are 8 reasons that error might have happened (search for ERR_HTTP2_PROTOCOL_ERROR on that page)

If you want to know specifically which, capture a NetLog. The resulting log file will have a textual explanation of what triggered the protocol error.

We expect this is a server side issue.

I can help you extract the information if you provide me with a NetLog.

Very much apprechiated if you can help!

The server sent an invalid header of "access-control-allow‌​-credentials":

t=49885 [st=  45]    HTTP2_SESSION_RECV_INVALID_HEADER
                     --> error = "Invalid character in header name."
                     --> header_name = "%ESCAPED: access-control-allow%E2%80%8C%E2%80%8B-credentials"
                     --> header_value = "true"
t=49885 [st=  45]    HTTP2_SESSION_SEND_RST_STREAM
                     --> description = "Could not parse Spdy Control Frame Header."
                     --> error_code = "1 (PROTOCOL_ERROR)"
                     --> stream_id = 1

The server serving https://tfnsw-2-1-preprod.pegacloud.net/prweb is sending an invalid HTTP header, which is why there's a ERR_HTTP2_PROTOCOL_ERROR.

t= 1729 [st=  211]    HTTP2_SESSION_RECV_INVALID_HEADER

                      --> error = "Invalid character in header name."

                      --> header_name = "http strict-transport-security"
                      --> header_value = "max-age=expireTime"
t= 1730 [st=  212]    HTTP2_SESSION_SEND_RST_STREAM

                      --> description = "Could not parse Spdy Control Frame Header."
                      --> error_code = "1 (PROTOCOL_ERROR)"
                      --> stream_id = 1

The space in the header name is invalid: RFC 7230 (section 3.2) specifies the format of a header field name, and spaces aren't allowed. That web server is misconfigured.

The server is sending RST_STREAM frames with error code 8 (CANCEL). This seems like a server issue, not a chromium issue.

Hi, 

I just faced the error net::ERR_HTTP2_PROTOCOL_ERROR 200 recently. I suspect something wrong with the download stream. The server returns 200 Status code but the request still failed. The server is in a good state, not under high load.

Attaching the log (compressed because the filesize is ~25MB). Failed requests are random. Path of some failed requests in my case are:

/irm/rest/v1.14/ddr-export-configs  

/irm/rest/v1.14/ddr-export-configs 

/irm/rest/v1.14/proxy-sources 

/irm/rest/v1.14/target-apps 
...

Any help/hint about what caused the error is appreciated.

RST_STREAM can be sent by either endpoint. In this case it was sent by the server, and sent with the error code for CANCEL, meaning the server decided to cancel the stream. If the server were resetting the stream because the client did something wrong, it would have used a different error code. Hence this is a server issue.

Hi Nick,
Thanks for your quick reply! Though, I don't quite get how's it a server issue.

Per my understanding, RTS_SREAM is used by client (browser) to abort request. When server receives RTS_STREAM, it will stop sending the data, and so stopping the download for the full response body.

The RST_STREAM frame (type=0x3) allows for immediate termination of a stream. RST_STREAM is sent to request cancellation of a stream or to indicate that an error condition has occurred.

Perhaps some other error actually occurred here with the request?

Hi All, 

I'm having an issue with this error for a few of the resources on our site. However the error only happens intermittently. We thought it was server memory at first, but could reproduce the error with most of the RAM freed up. I will attach the NetLog.

Thank you,

John
