IMPORTANT Update

[Chartered Information Systems Pvt. Ltd.]

Dear Valued ASPs:

As a part of routine security hardening process, we are removing support for obsolete SSL/TLS cyphers from Mumbai DC servers (https://einvapimum1.charteredinfo.com/) serving GST/EWB/eInvoice APIs on 18 August, 2025, Monday (around 11:00 am).  

 

In case any ASP get errors like "connection refused", "error in secure channel support", "Unable to connect to remote server", or any error indicating SSL/TLS handshake issue are requested to contact TaxProGSP Helpdesk immediately. 

Once above changes settles within couple of days, we would be implementing similar changes to other servers (In Delhi DC) by 21st August, 2025.

 Please feel free to get in touch with us in case of any queries.

Thanks & Regards,

TaxPro GSP.
