Problems with the work of the Matthermost plug-in #40

Closed AnnSoldatova closed 3 years ago

AnnSoldatova commented 3 years ago

Good afternoon, I have a problem with the Matthermost plugin for my redmine. It stopped working on October 1. I guess this is due to the deprecation of the InedTrust root certificate. On the machine where Redmine is installed, the operating system is Centos 7.6.1810. Uploaded a new list of root certificates, including GlobalSignRootCA_R3, the certificate on the matthermost server from letsencrypt. I would be grateful for your help in resolving this issue, thank you in advance.

@AnnSoldatova This specific problem is not related in any way with this plug-in. However, here are a few, hopefully helpful, resources:

  4. just google for: centos 7 let's encrypt root certificate

@thanosk the problem is infact with the ruby working with httpclient, it does not read the OS default ca cert and in my case I had to tell the httpclient that this is a ca cert path and then it started working with it.
