Adobe Analytics 1.0 connector issue

Sudddenly Adobe analytics 1.0 connector is throwing an error today(25-01-2024). there are diffent errors while trying to refresh the data.
Errors:

1. Invalid credentials - but i am sure there is no problem with credentials see below images for the examples.

If any problem in the credentials, source step itself it asks for credentials / throws an error.

Note: With the same credentials I am able to fetch the datas in adobe analytics 2.0 but it is still in beta.

2. Data format error:(Please refer below screen shot)

note: This both errors are randomly comming while I try to refresh data and Till yesterday from this post same file, same credentials, same connector is working completely fine.

Please let me know is there any maintenance is going on? or this is a separete issue.

Thanks in advance...,
