wpa_supplicant issues on android phone

**Disclaimer:** My knowledge of android as well as the inner workings of wifi connections are exceedingly limited. Additionally, I'm new to stackoverflow, so I might just be the worst customer you had... I'm having issues with my android phone (Fairphone 2). For some reason, I cannot connect to any new WiFi, i.e. ones I did not connect to before. The

logcat

shows the errors: 02-24 11:33:49.215 2221 3763 E WifiConfigStore: Failed to look-up a string: WPA_EAP 02-24 11:33:49.215 2221 3763 E WifiConfigStore: Failed to look-up a string: IEEE8021X 02-24 11:33:50.221 23048 7088 E WakeLock: GCM_HB_ALARM release without a matched acquire! 02-24 11:33:50.223 23048 7088 E WakeLock: GCM_CONN_ALARM release without a matched acquire! 02-24 11:33:50.857 25094 25094 E wpa_supplicant: nl80211: Failed to open /proc/sys/net/ipv4/conf/wlan0/drop_unicast_in_l2_multicast: No such file or directory 02-24 11:33:50.857 25094 25094 E wpa_supplicant: nl80211: Failed to set IPv4 unicast in multicast filter 02-24 11:33:50.858 25094 25094 E wpa_supplicant: nl80211: Failed to open /proc/sys/net/ipv4/conf/wlan0/drop_unicast_in_l2_multicast: No such file or directory 02-24 11:33:50.858 25094 25094 E wpa_supplicant: nl80211: Failed to set IPv4 unicast in multicast filter 02-24 11:33:50.860 25094 25094 E wpa_supplicant: nl80211: Failed to open /proc/sys/net/ipv4/conf/wlan0/drop_unicast_in_l2_multicast: No such file or directory 02-24 11:33:50.860 25094 25094 E wpa_supplicant: nl80211: Failed to set IPv4 unicast in multicast filter So I was thinking: I'm missing a file. Googling

I found [this](https://sysctl-explorer.net/net/ipv4/drop_unicast_in_l2_multicast/) webpage, so I tried to push a file of that name to the

/proc/sys/net/ipv4/conf/wlan0/

folder, but I cannot do that since my phone is not rooted. Interestingly, I found out this morning that I can connect to the open (unencrypted) wifi at my university. My Android version is 7.1.2 I have literally no idea what is going on, so any help would be much appreciated, especially since I reset all my network settings (before I knew the issue is related to new WiFi connections in general, not just the new one I got at home), so now ALL WiFi networks are new to my phone. Thanks a bunch in advance *Edit:* Added some more of the error log
