curl php HTTP/2 stream 0 was not closed cleanly

Question

I am trying to send a request using cURL and PHP and it throws an error.

HTTP/2 stream 0 was not closed cleanly: PROTOCOL_ERROR (err 1)

I am sending CURLOPT_HTTP_VERSION like this

curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_2_0);

cURL info printed with curel_version() is

Array

PHP version: PHP Version => 7.3.2

installed with homebrew.

I have tried almost all of the solutions here on SO, but still getting the same error. Do I need to download and compile PHP from source? Any clue/suggestion would be a huge help. Thanks.

Does it report this for all HTTP/2 sites or just one particular? – Storfer

for all, I guess, I have tried to connect to 3 different ones, same.. – Sinter

@Sinter : did you received any solution for this error ? – Oao

@AkhileshKumar: unfortunately, no, I was developing an automated script at that time, so I move forward with Python Scrapy. – Sinter

Answer 1

I had a problem similar to this and there was 2 things I needed to check for.

If you're using apache, in /etc/apache2/sites-available/[x].conf look for a line similar to this: Protocols h2 http/1.1

[x] = the name of the website's configuration file such as 00-default

For me I had Protocols h2 https://1.1 and that caused me to have the bug.

Alternative: run this command on your server "grep -ir 'upgrade' /etc/apache2/" Find the file that has the upgrade to http/2 and comment out the line.

I used this code and solve my problem.

curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
