Metatrader 4 crashes with Trading Central indicator

New comment
 
Hello,

I would like to share the following problem and solution, if any other has the same problem. It took some time to find out.

Problem is: After installing the Trading Central (TC) plugin and adding it to chart, the Metatrader closed with no error.
What happened? The TC plugin tries to contact "www.google-analytics.com", but the domain was blocked via DNS by a pihole (firewall).

Workaround: I have whitelisted the domain in pihole, but Whitelisting "www.google-analytics.com" permantly is not the solution. I have filed a bugfix-suggestion as well.

Error Message in Windows-Logs:
