Hello Ragil

Seems like the server of your journal cannot connect to pkp.sfu.ca domain.
You can try to ping pkp.sfu.ca on you server and if it is get connection loss, you should contact the server administrator to whitelist the pkp.sfu.ca domain.

Are you using a multi-journal ADS system?
Could you disable the “plugin update manager” and check again please?

Dear @ragil_nurhawanti

You can check firewall setting on your server and related configuration in your server to allow external connection.

Better bet, I guess you discuss this issue with the server provider or server administration since it is not OJS issue but actually server config issue.

I do have the same problem. There is no issue with the firewall. I tried the command
PING pkp.sfu.ca (208.70.244.23) 56(84) bytes of data. it took forever. I tried from a different server without a firewall, again it did not work.

I would highly appreciate your support.
