Server blocked or blacklisted when accessing pkp.sfu.ca (more than 30 journals affected)

Dear PKP team,

We are experiencing a recurring issue with one of our servers while trying to access the following URL:

https://pkp.sfu.ca/ojs/xml/ojs-version.xml

The error returned by curl is:

curl: (56) OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 0

This is the same problem we faced earlier this year. We maintain multiple OJS installations, and this particular server hosts over 30 OJS Installations, making it critical for our operations. Interestingly, we are only seeing this issue on this specific server; other servers with similar configurations are working normally.

We suspect that our IP address may have been blacklisted or rate-limited by PKP’s infrastructure.

This issue is preventing access to key features within the OJS interface, such as the Plugin Gallery and Website Settings, which rely on communication with the PKP network.

Please let us know if you need the IP address or any additional logs.

Aditionally, our server IP address is 162.240.164.240

Hi @Eder_Sotto,

I brought this up with our systems team and they added your IP to the allow list. Could you re-test to see if the error persists?
