Thank you @alona-lip for the proposed fix. However when I try your https://github.com/matomo-org/piwik-dotnet-tracker/pull/79 fix for this problem, I still get an HTTP 400 error. The called URL is :
https://piwik.<our domain>.com/piwik.php?idsite=11&rec=1&apiv=1&r=250779&cip=::1&_idts=1611940818&_id=7b2be05759a2bc7d&url=http%3a%2f%2flocalhost%2fdefault.aspx&e_c=mycat3&e_a=myact3
Currently I'm stuck not being able to call the tracking API from .NET. We have Matomo 4.1.0.
Hello @epos , Are you sure that your problem has really something common with this PR ?
I did not have 400. I had OutofRange Exception by LoadVisitIdCookies.
These changes should be tested from the Matomo Side (after they fix the CI Build Problem), and should be as an Update to Piwik.Tracker 3.0.0.0 (Nuget-Package) provided.
How did you test it? Have you compiled the changes and made the Nuget-Package by yourself?
Hello @tsteur , could you please test this PR as soon as possible and provide the Update to Piwik.Tracker 3.0.0.0 The Update of Piwik.Tracker (.NET) Nuget Package ist critically important for us.
Thanks & Best Regards, Alona
@alona-lip Thank you very much for your Pull request submissions, very appreciated!
I have merged it for now as we have no maintainer currently in the project, have just created a new issue: https://github.com/matomo-org/piwik-dotnet-tracker/issues/80

Thank you for your answer @alona-lip. The problem was indeed not due to this PR, but I couldn't know this at the time of asking since I was also struggling with the visitor cookie structure change. I isolated that other problem, and created a proper issue :
https://github.com/matomo-org/piwik-dotnet-tracker/issues/81
Hi there,
this issue refs https://github.com/matomo-org/matomo/issues/16397#issue-694540064
in Matomo 4 we're changing the structure of the visitor cookie. I don't know if this SDK reads the cookie of a visitor if one is set?
In the PHP tracker we had to make this change because of it https://github.com/matomo-org/matomo-php-tracker/pull/79/files#diff-cd22a4ca6eb55e6a5ad813334624ed89L1370-L1840
The cookie was changed in https://github.com/matomo-org/matomo/pull/15774/files#diff-1279d666063b65e6d6777f902d11574fR3322-R3330
It used to contain 6 indexes (newVisitor, uuid, createTs, visitCount, currentVisitTs, lastVisitTs) but now contains only indexes: Slot 0: newVisitor Slot 1: uuid Slot 2: createTs
Basically, if this tracker does read the cookie, then the tracker needs to be changed to only read the first to slots from the cookie (cookieVisitorId and createTs) see https://github.com/matomo-org/matomo-php-tracker/pull/79/files#diff-cd22a4ca6eb55e6a5ad813334624ed89L1370-L1840
All other information from the cookie list visit count, currentVisitTs, lastVisitTs is no longer needed in Matomo 4.
If this tracker does not read any cookies then it can be ignored.
