Hi, I've had a PWS uploading to Wunderground with Weewx 3.9.2 on a Raspberry Pi for several months. Yesterday the station randomly stopped uploading to WU although my local database is still being updated. Checking the log shows the following:
restx: Wunderground-PWS: Failed upload attempt 1: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:661)> Elsewhere in the log I found the actual URL that is being queried by weewx and when I run that manually with curl I get the following: user@host:~$ curl -L "https://weatherstation.wunderground.com/weatherstation/updateweatherstation.php?action=updateraw&;<redacted>" curl: (60) SSL certificate problem: unable to get local issuer certificate More details here: https://curl.haxx.se/docs/sslcerts.html curl performs SSL certificate verification by default, using a "bundle" of Certificate Authority (CA) public keys (CA certs). If the default bundle file isn't adequate, you can specify an alternate file using the --cacert option. If this HTTPS server uses a certificate signed by a CA represented in the bundle, the certificate verification probably failed due to a problem with the certificate (it might be expired, or the name might not match the domain name in the URL). If you'd like to turn off curl's verification of the certificate, use the -k (or --insecure) option. I've tried this on 2 other systems (another RPi and a CentOS VM) with the same result. I'm not that familiar with SSL certificates but when I check the one for weatherstation.wunderground.com one in my browser it says "valid". Is anyone else having this problem? How can I fix this issue? Thanks in advance. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
