Description

Upgraded docker on the Ubuntu 24.04.3 server to docker-ce 29.2.1 throws 404s on the frontend, and in the backend I get the following error from traefik. Anonaddy appears to be forwarding normally.

traefik | time="2026-02-03T00:51:34Z" level=error msg="Provider connection error Error response from daemon: client version 1.24 is too old. Minimum supported API version is 1.44, please upgrade your client to a newer version, retrying in 8.062669276s" providerName=docker

Perhaps a newer version of traefik in compose.yml might fix this?

Expected behaviour

Not 404

Actual behaviour

404

Steps to reproduce

Updated docker via apt

I think part of the problem was a full disk, however I'm still getting a 404, now with thousands of:

time="2026-02-03T01:49:01Z" level=error msg="accept tcp [::]:443: accept4: too many open files" entryPointName=https

I'm also getting the following in the DB container:

2026-02-03 9:16:42 19 [ERROR] Incorrect definition of table mysql.column_stats: expected column 'hist_type' at position 9 to have type enum('SINGLE_PREC_HB','DOUBLE_PREC_HB','JSON_HB'), found type enum('SINGLE_PREC_HB','DOUBLE_PREC_HB'). 2026-02-03 9:16:42 19 [ERROR] Incorrect definition of table mysql.column_stats: expected column 'histogram' at position 10 to have type longblob, found type varbinary(255)
