> [@sergioaema](#): > > i/o timeout" Welcome @sergioaema That looks like a communications timeout error and not a problem with the certs. Most likely some sort of firewall maybe blocking port 443 from the public internet? You say you can reach the website with `https://influx.w2.enkrott.com/` but I cannot. Could this be the problem? See this SSL Checker website which also cannot see that domain using HTTPS > **[SSL Checker](https://decoder.link/sslchecker/influx.w2.enkrott.com/443)** > > Verify that your SSL certificate is installed correctly, identify installation issues if any. ---

Is there some analytics, from say a CDN, that are not able handle the TLS levels and Ciphers you have available for client services and apps to connect with? Some security scanning services? ---

That's an influxdb "info" level entry. You should ask about this on an influxdb forum. Many services have nearly useless "info" level entries and adjusting the log level suppresses the messages. And, many times they are just nuisance messages. Now, this does seem like something that might be a problem. But, again, a forum of influxdb experts are best to advise you. I don't have any trouble accessing that domain:port which shows the certs are fine. A timeout problem can be caused by a wide variety of things. ```plaintext curl -I https://influx.w2.enkrott.com:8086 HTTP/2 200 last-modified: Wed, 28 Dec 2022 21:04:13 GMT x-influxdb-build: OSS x-influxdb-version: v2.6.1 openssl s_client -connect influx.w2.enkrott.com:8086 Certificate chain 0 s:CN = influx.w2.enkrott.com i:C = US, O = Let's Encrypt, CN = R3 a:PKEY: rsaEncryption, 2048 (bit); sigalg: RSA-SHA256 v:NotBefore: Apr 7 16:36:30 2023 GMT; NotAfter: Jul 6 16:36:29 2023 GMT 1 s:C = US, O = Let's Encrypt, CN = R3 i:C = US, O = Internet Security Research Group, CN = ISRG Root X1 a:PKEY: rsaEncryption, 2048 (bit); sigalg: RSA-SHA256 v:NotBefore: Sep 4 00:00:00 2020 GMT; NotAfter: Sep 15 16:00:00 2025 GMT 2 s:C = US, O = Internet Security Research Group, CN = ISRG Root X1 i:O = Digital Signature Trust Co., CN = DST Root CA X3 a:PKEY: rsaEncryption, 4096 (bit); sigalg: RSA-SHA256 v:NotBefore: Jan 20 19:14:03 2021 GMT; NotAfter: Sep 30 18:14:03 2024 GMT ``` ---
