Most probably it's a matter of missing or not properly working correlation <https://jmeter.apache.org/usermanual/jmeter_proxy_step_by_step.html#correlate-start>
In the absolute majority of cases you cannot replay the recorded script "as is" as modern web applications widely use dynamic parameters i.e. for client-side state tracking <https://www.c-sharpcorner.com/UploadFile/225740/what-is-view-state-and-how-it-works-in-Asp-Net53/> or security <https://docs.microsoft.com/en-us/aspnet/web-api/overview/security/preventing-cross-site-request-forgery-csrf-attacks> You need to identify all these dynamic parameters, extract them from the previous responses using a suitable JMeter post-processor, <https://jmeter.apache.org/usermanual/component_reference.html#postprocessors> save them into JMeter Variables <https://jmeter.apache.org/usermanual/functions.html> and replace recorded values with the variables.
