Hi,
Unfortunately, I can’t update to PMM v3.1.0 via the UI. When I try, I get the following error:
“Failed to check watchtower host”
Both Docker Compose configurations use the same WATCHTOWER_HTTP_API_TOKEN
. The update page also correctly displays information about my PMM instance.
Do you have any idea why this error occurs?
Thanks!
Hey @Marvin_Stelter ,
I take it you launched a docker container with watchtower? And you did this inside a dedicated docker network? And both watchtower, and pmm-server containers are in the same network?
Hi, i have same issue
both containers are in the same docker network

I have the same issue. I am trying to upgrade PMM from version 3.0.0 to 3.1.0 but I end up with the same issue - “Failed to check watchtower host”.
# docker inspect pmm-network

Im having the same issue here, both containers pmm-server and watchtower are in the same network , token and watchtower hostname are correctly set , but the update app wizard still complain about it is unable to check watchtower host.
I made it manually .
Stop and remove ctnr
docker stop pmm-server && docker rm pmm-server
percona/pmm-server:3.2.0
docker run --detach --restart always \
--publish 443:8443 \
--env PMM_WATCHTOWER_HOST=9436f0c11113 \
--env PMM_WATCHTOWER_TOKEN=28955d573bd9f89e267aeb9d0a11111c \
--volume pmm-data:/srv \
--network=pmm-network \
--name pmm-server \
percona/pmm-server:3.2.0
check new version
docker exec -it pmm-server bash -c 'pmm-admin --version'
results
