I've finally decided to migrate my old domain from http to https via LE just hours ago and I noticed now that it's no longer on Bing. I've got an A+ on ssllabs but I read this on reddit So another link is - HTTPS: Which cipher suites does Bingbot support? and according to the ssllabs result, I match 3 ciphers in there Code (Text): TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256 (0xc027) ECDH secp256r1 (eq. 3072 bits RSA) FS 128 TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 (0xc028) ECDH secp256r1 (eq. 3072 bits RSA) FS 256 TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA (0xc013) ECDH secp256r1 (eq. 3072 bits RSA) FS 128 and I only need one Code: please ensure your site is configured to use at least one of the cipher suites called out below Do I need a paid SSL to solve this? I'll be googling some more but I just want to know what you guys think.
