The marketing cloud is, as indicated by your SOAP response, experiencing an interruption.
When you suspect things aren't as they should be with a Salesforce product, the place to check is usually the "trust" site, https://trust.salesforce.com. For marketing cloud, that's https://trust.marketingcloud.com/
Salesforce Marketing Cloud is currently experiencing performance degradation that is impacting Stacks 1, 4, 5, 6, 7, 8, and 10 of the Marketing Cloud environment. During this performance degradation, customers may be experiencing difficulty in logging in to their Marketing Cloud services.
This is likely causing your issue. Please continue to monitor availability on https://trust.marketingcloud.com
If you continue to have issues once systems are restored then please report your question with some code samples
