Getting "There was an error adding Trello to Slack" when try add Slack app int to Trello Workspace

Hi @vyacheslav_klevchenya 

Welcome to the Community!

Regarding your question, is it possible that you have "block 3rd-party cookies" enabled in your browser or any browser extensions which are related to blocking third-party tracking or ads? Temporarily disabling those might help you to go through the authorization step. Another option is to use another browser to connect Trello to Slack. Once you are authorized, it should work in any browser.

Let me know if that helped to resolve your issue.

Thanks, @Vitalii Saienko a lot for your suggestion! Yes, disabling uBlock extension helped to solve the issue. Currently connected.
