node.js - Node axios script fails with 414 error in only one of three environments

Question

When querying an on-prem server's REST API using the same node.js script, 2 of 3 clients have a 100% success rate (Status 200). The third client has a 100% failure rate, with 414 errors.

Client	Status Code	OS	Node Version	Axios Version
Client 1	200	MacOS 10.15.7	Node 14.18.1	Axios 0.21.4
Client 2	200	Ubuntu 18.04.5	Node 14.10	Axios 0.21.1
Client 3	414	MacOS 11.4	Node 14.18.1	Axios 0.21.4

You can see client 1 and 3 are virtually identical, yet client 3 fails every time and client 1 succeeds every time. Client 2 uses a different os and package versions, yet succeeds as well.

The problematic request is the third in a chain. The first two requests succeed on all three clients. The third request is large, a POST with a body size of 266k.

We have inspected the headers, request objects, etc and have found no discrepancies (though may have overlooked something.) Where lies the gremlin?
