Dear member,
Thank you for posting your question on the Q&A platform.
Need clarification here, what do you mean by "Biztalk Visual Studio project cannot connect to Biztalk", is it possible to share the screenshot of the working configuration and not working error?
Here I would suggest a couple of things that you can check,
- Check if you are using the same account or the account that use for VS have access to BizTalk VM as well.
- Check if you are able to connect BizTalk databases from your local machine where Vs is installed.
- Check if TCP/IP is enabled on BizTalk VM.
Regards,
Kamlesh Kumar
