Bug description

The Plugin isn't working the error is:

Traceback (most recent call last):
File "/usr/local/lib/LinuxFabric/check-plugins/kemp-services/./kemp-services3", line 199, in 'module'
main()
File "/usr/local/lib/LinuxFabric/check-plugins/kemp-services/./kemp-services3", line 152, in main
base64.b64encode(args.USERNAME + ':' + args.PASSWORD)
File "/usr/lib/python3.9/base64.py", line 58, in b64encode
encoded = binascii.b2a_base64(s, newline=False)
TypeError: a bytes-like object is required, not 'str'

if I change

base64.b64encode(args.USERNAME + ':' + args.PASSWORD)

to

base64.b64encode(bytes(args.USERNAME + ':' + args.PASSWORD, encoding='ascii'))

I get the error

HTTP error "401 Unauthorized" while fetching https://********:443/access/listvs

but my credentials are correct
