Error when trying accessing data remotely: No url map found

[IsaacZ10]

Describe the bug

Not able to retrieve data when using Maps.

To Reproduce

Just trying to run a simple command, which used to work the day before. I've already updated the marvin to the latest version.
code and report:

In [9] : maps=Maps('7443-12703')                                  
[WARNING]: Cannot retrieve URLMap. Remote functionality will not work: a bytes-like object is required, not 'str' (MarvinUserWarning)

Desktop (please complete the following information):

• Ubuntu 16.04 LTS
• Version of Marvin [e.g. 2.0.2]

Additional context
Also not able to access the Marvin-Web, which shows 502 bad gateway.
But downloading data with rsync (following https://www.sdss.org/dr17/manga/manga-data/data-access/) is fine.
