SSS Website Design Improved but my.SSS Registration Malfunction

The Social Security System or SSS has launched its enhanced website that allows SSS members
and employers exclusive access to their social security records and to submit transactions

To access the SSS Website go to: www.sss.gov.ph  and register at My.SSS portal.

Through the My.SSS portal of the enhanced SSS Website, you can submit salary loan applications and maternity notifications online, view and print your social security records, set appointments with your servicing branch and download forms. If you are an employer, you can view and download your employer records and submit transaction reports online.And if you are also a household employer, you can use the My.SSS portal to submit the collection list of your househelper/s.

The SSS provided a PDF handbook as your guide for registration: https://ww2.sss.gov.ph/sss/DownloadContent?fileName=SSSForm_MySSS_Brochure.pdf

Registration Email Validation Error
I don't the online account yet so, I decided to register.The first form where you're going to put up your SSS number, name, email address goes through for me and I check my inbox for the confirmation email. I got the email however, when I proceed with the confirmation link this error message surprise me:
Error 404--Not Found
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.5 404 Not Found

The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.

If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.

I don't know what's exactly the problem but I guess its technical.Hopefully, SSS will fix it soon so we members could start transacting online conveniently.
