We have our F5 in our environments (lab and prod).
The site works fine when a customer logins, but when customers test our websites using Qualys, we see errors in the F5 ltm logs. We are running ltm version 12.1.1 HF1. We can change the cipher to any cipher suite from DEFAULT to ALL to custom and we see these errors in the ltm log:
Connection error: ssl_select_suite:6942: no shared ciphers (40)
Connection error: ssl_select_suite:6879: TLS_FALLBACK_SCSV with a lower protocol (86)
Connection error: ssl_hs_rxhello:7169: insecure renegotiation disallowed (40)
Connection error: ssl_hs_rxv2hello:8155: unsupported version (40)
Any help would be great.
