[BUG] Invalid usernameor password upon connection about check_pve

Does this also happen, if you're using the token based Auth method? See Readme for an example. Token based Auth is recommended with never proxmox versions

Yes, by two ways: I created an api token at the command line as given in your guide and in a second try from scratch where I tried by creating the api token in the gui. Result is the same.

./check_pve.py -u 'nagios@pam' -p "" -k -e 10.10.7.9:8006/api2/json/ -m version -V 8.0.0

API endpoint must not contain any paths. Endpoint and port can be specified via cli args and from that the check script composes the complete url. E.g. ./check_pve.py -u 'nagios@pam' -p "<pass>" -k -e 10.10.7.9 -m version -V 8.0.0

That solved it. Thank you very much.
Maybe it would be worth to mention this in the documentation part. This site always refers to an API_ENDPOINT. The official Proxmox API doc (https://pve.proxmox.com/wiki/Proxmox_VE_API) states under API URL the full path.
Additionally, as it seems this script here always adds the port. Luckily I am using the default port. Would not know what to do if I would use any other port.

Fixed with #52
