Matomo Cloud - Javascript Tag - Server returns 400

Adaptive · November 4, 2021, 10:22pm

I have a paid account for Matomo Cloud. I have tried to contact support, but did not receive any contact so far.

I have implemented the Matomo tag on my website, however, the server is returning a 400 code. Some traffic make it through the platform, but most of the traffic is being lost.

Follow an example of the hit failing -

https://“myinstance”.matomo.cloud/matomo.php
?action_name=Mywebsiteurl+title

&pf_srv=112
&pf_tfr=18
&pf_dm1=626
&pf_dm2=837
&pf_onl=16
&pv_id=hcwoDL

I have changed the parts that could identify my client. This is quite urgent and although the Matomo Cloud says they offer support, I did not receive any response from them so far.
I have tested to create a new measurable, I get the same error.

Please, see attached the point of the code where it fails -

Any help would be appreciated.

Thank you!

Can you share the HTTP error message? You can see it in the network activity tab of the browser developer tool…
@lukas any idea?

Hi, Phillipe, thank you for the reply.

Please, find below the information. I hope that is what you are looking for (including the server response on the next reply as I can only upload one image per post).
