We experience an issue while opening our Grafana dashboards using an iPhone SE.
Some of the graphs are disappearing while refreshing.
I can`t reproduce it with any other device and it seems to occur since we updated to this Grafana version.
Is there any known issue with this version / device?
Hi @emob,
Welcome to the 
community support forums !!
We are excited that you joined our OSS community. Please read about some of the FAQs in the community 
Could you please change the default log level to debug mode. To do this go to the server where grafana is installed and edit the configuration file (/etc/grafana//grafana.ini)
There you will this section;
#################################### Logging ##########################
[log]
# Either "console", "file", "syslog". Default is console and file
# Use space to separate multiple modes, e.g. "console file"
;mode = console file
# Either "debug", "info", "warn", "error", "critical", default is "info"
;level = info
Set the parameter level to debug and remove the colon in the beginning i.e.
level = debug
Then restart the grafana service and resent the logs once the issue occurs again.
Hello and thank you for your reply!
Now I have a log file where the issue ocurred, but I am not allowed to upload it here because of the file ending .tgz.
Is there any other possibility for me to share the log file under my post?
Thank you.
Hi @emob,
Well, you can use some free online tools to upload your tarball log file and send the link.
I think https://www.ezyzip.com/ seems easy.
However, please remove any sensitive data as we are not responsible as we do not maintain those tools and any data-privacy rules.
Also as an alternative you use pastbin tool which though only allows you to copy/paste the logs and then set the link to expire e.g. in a week or month etc.
Thank you.
The error should ocurr at 12:08
I don`t know why it disappeared - another try
Same, I think you posted as a private user?
yes - I made an account now. Hopefully it won`t be deleted.
Ok so I created my own account
Now I see that your post is in process of moderation, once get approved then can view it 
Oh I see - thank you for clarifying!
I used another file sharing service.
I hope it is available for you now.
Log File
Edit*
The file above also has been deleted.
Here is another Link https://file.io/OiNTdECeELci
I explained the content of my upload to pastebin and they restored my post:
Thanks. I have looked into the logs but not v.clear why this is happening
We would appreciate it if you can open a bug report about this in our official GitHub repository using this link.
Provide all the information (you can simply copy/paste your data + screenshot from here to there).
Lastly, paste the link to your GitHub issue here so that all other community users can also track it (i will add more information into it as well).
Thank You!
As suggested I`'ll open a bug report and I am looking forward to getting more insight of the issue.
I created a bug for this issue:
iPhone SE: Graphs disappear after refresh · Issue #65418 · grafana/grafana (github.com)
Thanks. I will add more metadata to it.
