Hello Jarek,

This may occur if there are firewall restrictions causing the import to be
blocked, that could be confirmed/tested by running local tests. We have also
seen this issue if there are many Charts importing on the same page but the
symptom in this case might only occur on some of the Charts. I am not aware
of any problems associated with SOAP so I can't rule that in/out just yet.

If it is a security issue There may be an alternative technique allowing you
to import the ascii based Base64 stream (as mentioned in your other recent
post) though you would have to export that as your own stream variable.
There is no direct TChart LoadFromBase64URL .... though if the issue lies in
this area we could study the possibility to include it in a future version.

Regards,
Marc Meumann
