Hi. Have trouble with dhcpcd. Sometimes, when i run # dhcpcd wlo1, when i connected throw wpa_supplicant to my router, i have something like this:
# dhcpcd wlo1
DUID 00:04:33:44:43:35:33:32:38:37:4a:35:d4:c9:ef:6d:b0:66
wlo1: IAID 2c:c7:3f:f9
wlo1: adding address fe80::662e:686d:a3c8:740d
wlo1: soliciting an IPv6 router
wlo1: rebinding lease of 192.168.1.34
wlo1: NAK: from 192.168.1.1
wlo1: soliciting a DHCP lease
wlo1: no IPv6 Routers available
timed out
dhcpcd exited
Or sometimes like this:
# dhcpcd wlo1
DUID 00:04:33:44:43:35:33:32:38:37:4a:35:d4:c9:ef:6d:b0:66
wlo1: IAID 2c:c7:3f:f9
wlo1: soliciting a DHCP lease
wlo1: soliciting an IPv6 router
wlo1: no IPv6 Routers available
timed out
dhcpcd exited
And if it works correct, it shows this:
# dhcpcd wlo1
wlo1: waiting for carrier
wlo1: carrier acquired
DUID 00:04:33:44:43:35:33:32:38:37:4a:35:d4:c9:ef:6d:b0:66
wlo1: IAID 2c:c7:3f:f9
wlo1: adding address fe80::662e:686d:a3c8:740d
wlo1: soliciting a DHCP lease
wlo1: soliciting an IPv6 router
wlo1: offered 192.168.1.34 from 192.168.1.1
wlo1: probing address 192.168.1.34/24
wlo1: leased 192.168.1.34 for 604800 seconds
wlo1: adding route to 192.168.1.0/24
wlo1: adding default route via 192.168.1.1
forked to background, child pid 1394
And if i no mistake, dhcpcd -4 wlo1, not help (but i will try test one more time, problem old on my laptop, but sometimes it is appear)
Yesterday i tryed to fix it, and i spoiled wlo1 interface

No , i just after boot, start my sript(it just choses file with config, and starts wpa_supplicant and dhcpcd)
But trouble in NetworkManager, yes?

Yes as noted here multiple programs trying to control the same interface leads to the strange behavior you are seeing.
