Connecting bank accounts

I get this error message when trying to connect a bank account.

How are you trying to connect the bank account? Also provide much more details as per FAQ - Manager Forum which states:

Be specific. Do not just tell us a feature does not work. Explain what you have done and why you think there is an issue. If your question relates to an apparent software problem (rather than an accounting topic), tell us your operating system (including the version), Manager edition (desktop, server, or cloud), and exactly what you think is wrong. If possible, post screen shots illustrating the problem.

Note that I added it to bugs even though it indicates “Malformed URL” meaning that either the URL is misspelled and/or port assignment wrong, it threw an exception error.
