I followed this guide with additional changes:
I assigned a static IP to eth1 (I don't not if it is relevant)
I changed all my dockers to br1 with a static IP
Docker custom network type: macvlan
Host access to custom network: enabled
I have 11 days without any crash, the only problem I have is with Nextcloud or FileBrowser, when use a static IP, it set the default port to 80/443 (I cannot change them) creating conflict with Nginx Proxy Manager. If I use Bridge/Host option the IP assigned is from the br0, not br1.
