First of all, it looks like the problem arises with every new Windows installation on different machines. So this seems like a general buck. I hope a developer can test this to see what the problem is.
Update 1: First look at my update at the end of the text to easily test it.
Update 2: Look at the first answer of the post for better error description.
Odoo version: Odoo 14.0-20211126 (Community Edition)
Testet also with Odoo 15
I'm creating an HTML e-mail with "e-mail marketing". Here I add various links and also internal links of my odoo-subpages. When I send a test email everything works fine, the links are not automatically converted to relative links (utm-links). When I send the mail to customers, the links are converted into relative links and and odoo converted them to utm-links for tracking.
If you open on one of the non working links in the e-mail, you will be directed correctly
to my page, but then the error 500 appears with the following text. :
500 - Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.
So it looks like the Odoo UTM-links does not work for incomprehensible reasons. The original link (relative link: http://site.mydomain.de/r/ZuJ/m/67) in the e-mail is corectly converted by Odoo when it is called and then appears in the address bar of the browser the UTM-Link:
https://mydomain.domain.de/kontakt?utm_source=testtest+2021-11-27+22%3A58%3A22&utm_medium=Email
Mydomain is of course my correct web address. So the redirection works correctly.
It looks like, every UTM-link, which are created below my homepage main page, are blocked. How can this happen? Does it maybe have something to do with the cookie settings on my site? (note my update at the end of the text)
Since I suspected a bug in the web server (IIS), I tested the whole thing directly on the server with localhost to bypass the web server. The error remains the same, so it is clear that it must be due to Odoo itself.
The following UTM-link was displayed:
https://localhost/kontakt?utm_source=testtest+2021-11-27+22%3A58%3A22&utm_medium=Email
It should also be mentioned that Odoo is addressed via a subdomain over the Internet. That shouldn't have anything to do with the bug, however.
Some utm-links work sometimes, but it also depends on whether I put them in the e-mail with http:// or https://. The link to my Odoo home page (only homesite) works, for example, and sometimes links external sites as well. However, Oddo internal sub-pages do not work at all.
I have now created a test database on Odoo.com and there I created a e-mail in E-Mail Marketing and added an internal link to a subpage of my own Odoo page. If I now open this link, the same error 500 on the UTM-link is also displayed on my page, although the whole thing was initially via the test database at Odoo.com. So my odoo site does not accept UTM links on all of my subpages.
I've tested this on different Windows machines. Even with completely new databases. The result is always the same, it doesn't work and the error is always the same. The Odoo versions are all up-to-date.
This message can be found in the log file (there is a different link like the one above, the error is the same):
ValueError: Setting 'domain' for a cookie on a server running locally (ex: localhost) is not supported by complying browsers. You should have something like: '127.0.0.1 localhost dev.localhost' on your hosts file and then point your server to run on 'dev.localhost' and also set 'domain' for 'dev.localhost'

Update:
If I generate a link with the "Link Tracker" module without assigning a "medium" or "source" to it, then this generated link works good. As soon as a "medium" or a "source" is assigned, the error 500 occurs when the generated link is opened. The problem already exists when only working locally with the localhost without a web server (Nginx, Apache or IIS). It is probably an internal problem of the Odoo web server "Werkzeug".
Additional error description and possible workarounds
Additional error description
The UTM link is wrong or generated incorrectly and therefore the returned URL is not functional.
The value ? within ?utm_source is not accepted.
If change "?" to "#" the link will work.
Examples of non-working URL and working URL
Not working URL:
https://sub.domain.com/book?utm_source=Test&utm_medium=Direct
Working URL:
https://sub.domain.com/book#utm_source=Test&utm_medium=Direct
The tracking link generated by Odoo is of course always used as the original link. Such as:
http://sub.domain.com/r/CQf
It is also possible to use the "=" sign ";" to be replaced so that the link works.
Working URL:
https://sub.domain.com/book?utm_source;Test&utm_medium;Direct
There are a couple of ways you can replace the characters to make the URL work.
Test on Linux-server
For comparison, on a Linux server the URL (link) work with the original characters:
https://12345.odoo.com/?utm_source=Newsletter&utm_medium=Email#scrollTop=0
Accordingly, the value is the same and there are no problems opening the link. The Odoo or Odoo-webserver (Werkzeug) programming on Windows also seems to have an error.
Basically, however, the URL should work with the default value and it should not be necessary to replace the character. So I am assuming that something has to be adjusted in the Odoo-programming under Windows so that the values „?" , "=" , "&" work or are accepted. However, I am not a programmer and don't know my way around so I can find a solution here. As long as this is not changed, however, no Windows installation will work correctly, regardless of which primary web server (IIS, Apache or Nginx) is used on the server.
The bug also existing in Odoo 15.
