Issue link is wrong in the notification message

[SinjinJang]

I have a problem that issue link in the notification message has wrong server URL.
More exactly, my redmine server URL is "http://192.168.0.200:8080/redmine", but the URL of issue link is "http://192.168.0.200/redmine/issues/961". [There's no :8080 port]
Because of this issue, I can't directly open redmine issue from slack notification.
Is this some redmine setting problem, or might be a plugin issue?
I tried to find out admin settings, but I couldn't find it yet...

Thanks in advance.

Oof... Having to massage the code, post-deployment, kinda wrecks deployment automation.

Note: found this issue because, after 300+ days, updated my RedMine version - and the plugins along with it - and now the links injected into my Slack channel are HTTP rather than the proper HTTPS. 😕
