SERVICE LAYER SAP BO TLS 1.0

0 Kudos

Currently we have SAP Business One 9.3 in my company, we want to make an integration of SAP with a web application developed in angular, however to make some requests to the url of Service Layer https://1.1xx.x.x:50000/b1s/v1/Login/

I get the error: ERR_SSL_VERSION_OR_CIPHER_MISMATCH

I understand that this happens because I have TLS Version 1.0, is it possible to update to TLS 1.2 in SAP BUSINESS ONE 9.3?

Alternatively, if SAP Business One cannot be upgraded to TLS 1.2, you can "downgrade" the SAP Business Connector to TLS 1.0. This can be done by logging in to the SAP BC UI as Administrator and going to

"Settings --> SSL Client Settings --> Minimum Protocol Version"

and setting this field to "TLS 1.0". You may also need to activate a few older out-dated Ciphers on the "Configure Cipher Suites" Screen.

what I did was configure an apache2 reverse proxy ignoring the certificate validation, now I want to try with nginx. Here is my configuration.

<VirtualHost *:<LocalServerPortForServiceLayers>>
ProxyPass / https://<SAPServerIP>:<ServiceLayersPort>/ connectiontimeout=60 timeout=60 Keepalive=On
ProxyPassReverse / https://<SAPServerIP>:<ServiceLayersPort>/
SSLEngine on
SSLProxyEngine on
SSLProxyVerify none
SSLProxyCheckPeerCN off
SSLProxyCheckPeerName off
SSLProxyCheckPeerExpire off
# ProxyErrorOverride On
SSLCipherSuite AES256+EECDH:AES256+EDH
SSLProtocol All -SSLv2 -SSLv3 -TLSv1 -TLSv1.1
SSLCertificateFile /etc/apache2/certs/<LocalServerCertificateForHTTPS>.crt
SSLCertificateKeyFile /etc/apache2/certs/<LocalServerCertificateForHTTPS>.key
</VirtualHost>
