For operating systems that are kept up to date, SSL certificates do not have to be installed manually in case of a certificate update.
If your system has problems connecting to SIGN DE V1 via www.kassensichv.io, it may be necessary to upload the certificates manually.
Below you can find the instruction on how to install the latest SSL certificate for www.kassensichv.io if it is not yet uploaded:
1. download the zip-File www_kassensichv_io_cert_chain.zip and unpack it
2. enter the following commands in the terminal (this will ensure that the cert chain is installed in the system):
certutil -addstore -f "Root" USERTrustRSAAAACA.crt
certutil -addstore -f "Root" SectigoRSADomainValidationSecureServerCA.crt
certutil -addstore -f "Root" AAACertificateServices.crt
Please note:
This process only affects version 1 of the SIGN DE API. The SIGN DE V2 API is not affected by the certificate update.
