Steps to replicate the issue (include links if applicable):

• Log out from TWL and, if needed, delete relevant cookies
• Log in to TWL
• In the TWL dashboard click on "Access collection" for Springer

What happens?:

• Since last night (central European time zone) his yields: "HTTP Status 400 – Bad Request" = Springer Link cannot be accessed over our proxy
• At the same time, https://link.springer.com/ can be accessed directly over the internet, so the site is up

What should have happened instead?:

• We should have access to Springer Link.

Other partners can be accessed, as expected. Only Springer is affected.

Could you please look into this?

Thanks in advance.
