Reason: CORS header 'Access-Control-Allow-Origin' does not match 'xyz' - HTTP
reason reason: cors header 'access-control-allow-origin' does not match 'xyz' what went wrong?
... simply put, the origin making the request does not match any of the origins permitted by the access-control-allow-origin header.
...the header itself accepts a comma-delineated list of origins, so adding a new origin is not difficult.

Reason: CORS request external redirect not allowed - HTTP
reason reason: cors request external redirect not allowed what went wrong?
... the cors request was responded to by the server with an http redirect to a url on a different origin than the original request, which is not permitted during cors requests.
... for example, if the page https://service.tld/fetchdata were requested, and the http response is "301 moved permanently", "307 temporary redirect", or "308 permanent redirect" with a location of https://anotherservice.net/getdata, the cors request will fail in this manner.

Reason: Did not find method in CORS header ‘Access-Control-Allow-Methods’ - HTTP
reason reason: did not find method in cors header ‘access-control-allow-methods’ what went wrong?
... the http method being used by the cors request is not included in the list of methods specified by the response's access-control-allow-methods header.
... note: if the server includes any unrecognized or undefined method names in its access-control-allow-methods header, a different error occurs: reason: invalid token ‘xyz' in cors header ‘access-control-allow-methods’.

Reason: CORS preflight channel did not succeed - HTTP
reason reason: cors preflight channel did not succeed what went wrong?
... the cors request requires preflight, preflighting could not be performed.
... there are a couple of reasons why preflighting might fail: a cross-site request has previously been performed that already did a preflight, and doing the preflight again is not permitted.

510 Not Extended - HTTP
the hypertext transfer protocol (http) 510 not extended response status code is sent in the context of the http extension framework, defined in rfc 2774.

...each object has a private property which holds a link to another object called its prototype.
...when trying to access a property of an object, the property will not only be sought on the object but on the prototype of the object, the prototype of the prototype, and so on until either a property with a matching name is found or the end of the prototype chain is reached.

types of error generally speaking, when you do something wrong in code, there are two main types of error that you'll come across: syntax errors: these are spelling errors in your code that actually cause the program not to run at all, or stop working part way through — you will usually be provided with some error messages too.
... logic errors: these are errors where the syntax is actually correct but the code is not what you intended it to be, meaning that program runs successfully but gives incorrect results.
