Regex for conversion matching not working correctly?

Hi,

I’ve been trying to count conversions with matomo when an URL with a certain URL pattern has been visited. The URL looks like this:

http://domain/keyword/keyword/1/2408

The regex we’ve created is this: domain/[^/]/[^/]/1/ which is correct according to regex101: build, test, and debug regex

But when using this regex in Matomo for conversion tracking, nothing happens.

Is there somethign wrong with matomo or could help me with a regex that works with matomo, please?

Best,

Paul
