Even though, I still have no idea why that happens.
please re-read the following lines of my last answer. What is unclear
about this?
Since it works now, it is clear, that the line-breaks caused you troubles.
The line-breaks are usual for base64 encoders (GNU uuencode, tcllib
base64::encode, ...), so ns_base64encode is just compatible with these.
The code in OpenACS, that David has pointed to, has therefore exactly
the same problem, when the encoded string starts to contain line breaks.
Usually userid+password are not so long as in your case, so this bug was
not noticed before.

Dear Iuri,
The problem, you are probably facing is probably that ns_base64encode
produces line breaks as required for MIME encoded text strings [1].
% ns_base64encode

Converting to and from a string with these linebreaks should be fine
for all base64 codecs (you see, colon is not the problem)
% ns_base64decode [ns_base64encode
Afrewf564DFSFSF54jgnfhgGDGdfRGRT43:7584fjhfjhf84jkrugrefAFFD9449474]
Afrewf564DFSFSF54jgnfhgGDGdfRGRT43:7584fjhfjhf84jkrugrefAFFD9449474
But probably, the header field has problems with linebreaks.
Therefore, simply remove the newlines by e.g.
set credentials [join [ns_base64encode
Afrewf564DFSFSF54jgnfhgGDGdfRGRT43:7584fjhfjhf84jkrugrefAFFD9449474] ""]
set req_headers [ns_set create headers Authorization "Basic $credentials"]
All the best

PS: In order to see, what is sent via and and/or node, use tcpdump
and/or wireshark, then you do not have to do any guessing, what is
exactly sent by which command in which implementation....
