Hello Nicolae and welcome to our forums,
First of all, thank you for your interest in Advanced Installer.
In what regards this behavior, this may happen if you are using our support for
"Digital Signatures", together with a Symantec certificate. By doing so, Advanced Installer may try to perform those requests in order to verify the timestamp of the certificate.
If so, could you please disable the digital signature support (by going to the "Digital Signatures" page --> uncheck the "Enable signing" option) and let me know if the behavior still persists?
Looking forward to hearing from you.
All the best,
Catalin
