TDS Correction statement submission not processing

Dear All,

I made correction in deductee salary details for error while filing original for Q4 of 2019-20 . Correction successfully went to correction ready for submission. But while submitting for processing, it is not responding. I have checked the browser compatibility and java config 8 (45) .Everything looks fine.I am the authorised person.I have done changes like this many a times in the previous weeks.All was working fine.Since two days I am facing issues. How to resolve this issue and submit the correction file with DSC?Is it an issue from CPC or my system? Any help is appreciated.
